FA's: great for picking up those pesky undesirable friends of a regular guy's sex target, especially if said pesky undesirable friend is fat.

(But really, who cares about anything other than appearances?)

hahaa yeah I dont know about this one
its playing on the concept that fat girls are desperate, chosen last and will be grateful for the attention.

I mean I dont know if its just where I live but when out clubbing a fat girl has way more chance of getting laid then a slim guy, because that's just the way it is, guys always hit on girls at the clubs so even fat girls dont have to take the fa wingman that is ' taking one for the team'

and also if I got any inkling that your friend was asking you to ' take the fat one ' as a favour.. I dunno maybe figured it out by your 'double pointy finger gun-clicky noise'

oooooo boy you would get it
