best overheard fight ever

[this_isnt_maybe]

okay, just to set this up properly, it looked like Guy was making Girl go on a bike ride she didn't really want to go on, and Guy wasn't being particularly understanding of the fact that Girl was getting extremely hungry

Guy: where are you going? i'm trying to help you here. there's a burrito place right around the corner, let's just go in the bike shop first
Girl: i'm not interested in going in that bike shop
Guy: look, i'm trying to mitigate my spending by not buying something for you that you could buy for yourself
Girl: i don't even know what it is that you want me to buy
Guy: it's a uh... a travel pump
Girl: i don't know what that is, so that means i don't need it
Guy: i don't know what a vasectomy is, that doesn't mean i don't need one!

gah, brilliant on so many levels. mean and derisive but also totally defensible. master of subtly insulting your girlfriend, teach me your ways!
