This is probably the wrong time to go on about how that trope sexualizes violence and encourages people to think that "no means yes" even given ever-more-stringent values of "no", isn't it?
I happen to like girls who initiate sex with this sort of challenge. It is a straightforward alternative to the verbal or social challenges that fill the same role more frequently. In fact playing out the dynamics so directly rather than in the verbal world helps prevent any confusion as to whether verbal expressions are a façade to test character or a boundary. 'No' could always mean 'no' and never mean 'I'm not comfortable yet, pull back and continue the mating dance'.
Rape is bad/evil/other/death-spiral. But this trope doesn't encourage rape.

2:59:02 PM Michael Blume: haha, yes ^^
3:00:40 PM Katja Grace: Plenty of discussion on why few girls, how to get girls, nobody ever says 'oy, girls on lw, want to get together some time?'
3:01:14 PM Michael Blume: somebody really should say that
3:01:34 PM Michael Blume: hell, I'm tempted to just copy that IM into a top-level post and click 'submit'
3:01:48 PM Katja Grace: Haha dare you to
