Learn English – How to explain the sentence “What do you make of the argument that…”

It means roughly the same thing as "here" usually means:

Bring the box over here.

I could use some help here.

Idiomatically, it is often said with extreme urgency:

I need some help here!

But there is nothing terribly abnormal about this usage. It just means "here", but more importantly.

here —

1. in this place: in, at, or to the place where you are, or at a place near you
2. at this point or stage: used to draw attention to a particular point or stage in a situation
3. now: indicates a situation or event that is happening at the present time

All three of these definitions would apply.

Both your example sentences are perfectly fine and exactly how people use the expression.

The Urban Dictionary definition is badly worded (if you’re just getting started with using Urban Dictionary, get used to this—most entries on there are horribly worded). What it means is that you can also say something like,

“Do matrix operations? Gah, I’d rather bleed from the eyes!”

This emphasises that even bleeding from the eyes is more appealing than doing matrix operations.
