You. I like you. I do similar things to fatties all the time, my personal favorite being deadlift day (way more weight lifted than them and the belt emphasizes my small waist).  I love their looks of defeat but I do look very strong too, so it's not as great an effect.  But I can just picture the shame in a fatty's face when he realizes that a girl is not just stronger, but MUCH stronger and that he is not "mostly muscle" as he tells himself.
