Whenever any guy makes any small mistake, there is always a women laughing at it for no real reason. I've noticed it twice this week.

A professor I TA for asked me to come to class one day but he sent me the wrong room number. I walk into the wrong class, the professor of that class asks me who I'm looking for, I said "oh sorry, wrong room" and left. And sure enough, multiple girls start giggling but not a single guy.

I then noticed it at my archery class later. My arm got sore near the end of the day so my shots got pretty lousy. My last shot didn't even hit the target at all and fell on the floor and sure enough, the women next to me gives me that smile that cartoon villians give when they are plotting something.

You have to be pretty messed up to see someone screw up and think to yourself "lol, a guy screwed up, that's so funny I need to burst out laughing"
