...proper bro-protocol is to be proud of said bro for pulling a hottie and perhaps slip him a fist-pound when she's looking elsewhere. Unless:
1. The bro has a popped collar
2. The hottie is your sister
3. The hottie is your ex-girlfriend
4. The hottie is your mom
5. The bro's jeans look like they belong to your younger sister
6. The bro still has a sticker on his hat (doubly so if the sticker says "new era" on it)
7. The bro is wearing make-up (...Chinook Mall, I'm looking at you)
8. The bro is wearing a V-neck t-shirt (doubly so if it's pink or purple)
