Your sense is not a stretch, although a bit too precise in the "simultaneously on both sides (above the hips, below the rib cage)" element.
- slang. To poke, tickle, etc., (a person) in a sensitive part, esp. the genital or anal regions; sometimes, more specifically, = fuck v. 1.
....
1906 Dial. Notes 3 138 Goose, to create nervous excitement in a person by pointing a finger at him or by touching or tickling him and making a peculiar whistle.
1932 J. T. Farrell Young Lonigan v. 205 Paulie slapped Denny's face. Denny bawled... Paulie goosed him. Denny squirmed.
...
1967 E. Partridge Dict. Slang Suppl. 1152/2 Goose, the predominant post-World War II meaning is ‘to jab a finger in ano, in order to surprise or annoy’.
["goose, v.". OED Online. September 2015. Oxford University Press. http://www.oed.com/view/Entry/80030 (accessed September 18, 2015).]
As you can see from the sequence of quotes and the meaning of the final one, if your sense was transmitted to you by someone, a grandparent for example, who learned the term before the end of WWII (during which the sense of 'to goose' was considerably vulgarized by soldiers), the sense you learned would correspond with what that person was likely to have encountered--aside from the precision I already pointed out.
Nonetheless, your use of the term with the sense you learned is now much more likely to evoke the more vulgar sense than what you intend, even imprecisely (a simple poke to startle)...although I, for one, depending on the context (and particularly the speaker or writer) understand it in the general sense "to poke, tickle, etc., in a sensitive part", rather than the more specific, vulgar sense commonly used.
If you're looking for a replacement phrase or term, what I've heard used is "a poke in the ribs", as in
1949 Lockhart (Texas) Post-Reg. 3 Mar. She laughed and gave him a discomposing poke in the ribs.
This is the common contemporary phrase closest in meaning to your sense of 'a goose'. Obviously it moves the location you specified upward on the torso, omits the simultaneous duality of your poke, and doesn't accommodate concise verbal use.
Thrifty might fit:
1 : thriving by industry and frugality : prosperous
3 : given to or marked by economy and good management
[M-W]
Palpably related to thrive, so there is a mild implication of prosperity in connection to the frugality. Frugal is a good option, too, even though it also connotes modesty, which I'm not sure is the case here.

The term in statistics and information technology is characteristics.
The more down-to-earth term is archetype.
The verb characterize connotes finding out the commonalities of a group of entities. The noun for that act is characterization. The adjective is characteristic.
For example, characteristic behaviour of a hero is their self-less devotion to public good.
For example, when a company introduces a new CPU, their engineers will perform characterization on various information gathered from its fabrication, and from tests observed due to a set of stimuli.
And then they might find seven rather distinct groups of CPUs that resulted from variations that occur in their manufacturing. So, for example, an engineer might advise the marketing concerning one of the groups, saying "This group of CPUs is characteristic of low performing devices, suitable for being packaged and sold as equipment controllers."
A company engaging in online sales of its product would seek to characterize their customers. The result would be conclusions about any customers like, "This customer is characteristic of a ponderous, highly researched customer." This customer is archetypal of a middle-aged afternoon-sit-coms mom.
A political campaign too would perform characterization of members of the electorate. For example, one might conclude, the voters in southwest Iowa are characterized by their slow temper, love for corn dogs and their penchant for hiring illegal immigrants.
What are the characteristics of a true dog lover?
My mom is archetypal of a large-breed-dog lover. She buys dog food by the truck load.
The archetypal behaviour of a Canadian truck driver is their disregard for traffic etiquette on US highways.
A mom-and-pop store is characterized by their having family members as employees, avoidance of low profit margin items and their familiarity with the personalities of their customers.
OTOH, you should consider the term archetype.
For example, The Maine farmer is archetypical (more properly, archetypal) of the hardy but volatile New Englander. When climate change made it too wet for potatoes, they farmed trees instead, and in fact sold their land to large corporations and then to work as employees for the tree farms.
archetype (ˈɑːkɪˌtaɪp)
n[from Latin archetypum an original, from Greek arkhetupon, from arkhetupos first-moulded; see arch-, type]
