In the Song "Ten Foot Cock And A Few Hundred Virgins" Tim Minchin uses the phrase "it's a sin to take it up the date, even if it's great, even with your cowboy mate". I'm not a native English speaker – I have lived in the UK for a bit and consider my English to be quite good for a foreigner, but have never heard "date" used this way. Is it used in English in that way, am I mishearing it, is it an Australian thing, or did the singer just make it up to have something that rhymes?
Link to that moment of the song (most likely not safe for work):

Date as a synonym of "anus" is Australian slang. The definitions I've found are a bit vague in terms of what specific anatomical feature it refers to (some say "anus," some say "buttocks"), but other people responding to this post have provided evidence that this vagueness may just be due to some dictionary-writers misunderstanding the meaning. (For example, rogermue found a definition that says it can also mean "vagina," but JEL found an Ozwords link where it says that "Later investigation concluded that the second meaning [vagina] was a furphy [false report]." Mark Cogan says that "This was reasonably well-understood slang (meaning 'anus') when I was at university in Australia in the early 1990s; it never meant any other orifice or the buttocks in general.")

I'm not Australian, so I can't describe this usage from a personal perspective.
