I've put my time in as wingman don't get me wrong, but there's a point where you have to draw the line.
If she weighs more than I can bench for 12 reps it's a no go. I haven't had to take one for the team in a while tho. Ins and my buddy find groups of girls that way there's more of them than us and we have more of a chance to get the hotter skinny ones.
I will say tho the biggest girl I had sex with was not fat she had the softball build to her. Most of the time I played wingman by talking to the less attractive one as afar as facial features.
