1. Bros before hoes. I cannot stress this enough. Always remember, girlfriends come and go, but your boys are always there. Breaking this rule is to commit the cardinal sin against Team Testosterone.

2. Never drink the last beer, unless you've been granted specific permission that it's OK.

3. If a girl falls into the following criteria, she is off limits forever until the end of time:

A. Was an ex-girlfriend.
B. Your friend specifically told you he wanted her.
C. Is you're buddy's sister.

However, if it's your buddy's cousin, well she's up for grabs, and you're welcome to rub it in his face for years to come.

4. Never diss a guy if his team just lost a crushing game.

5. You must never own a cat.

6. If you get 2 tickets to the big game, the priority list for granting the second ticket is as follows:

A. Your best friends (in order of how long you've known them).
B. Your acquaintances.
C. Your co-workers.
D. The mailman.
E. The UPS guy.
F. NASA.
G. John Kerry.
....Z. Your girlfriend.

7. You are allowed to enjoy exactly one chick TV show, and one chick flick. (Mine are Dawson's Creek and Love, Actually). You may have no more. And if you like Grease, well, we're already too late.

8. Birthday and Christmas presents for your guy friends are optional. Beer always makes a great gift.

9. If you go the bar with your buddies, you must buy a round of drinks at least once.

10. There are no mercy rules when playing someone in Madden, hoops, street hockey, bare-fisted boxing, Battlefield 3, etc.

11. If you owe someone money, pay them back as soon as humanly possible—unless it's a gambling debt, which must be paid immediately.

12. When out with the guys, never accept a call from your girlfriend—unless she's dying or trapped under a burning fuel truck, and if that's the case, make it quick.
