Is it just American men who flip their boxers/underpants into the air, then catch them, when they take them off? You know -- the ankle-flick maneuver? Or is this universal?
I have never seen this done either.. my (American) husband definitely does not do this. Come to think of it though, I've never really noticed his self-removal technique.. definitely no noticeable fancy moves as you have mentioned though.
Mine never did that until last night (after I told him off the night before for not putting them in the hamper, he decided to make a big spectacle out of it... sigh...)
It's something you'd probably only notice if you watch your husband remove his underwear. I remember when I was in college I saw a comedian who joked about this, and then I started paying attention. Ever since then, every guy I've ever seen remove his underwear has done this move.
