We’ve all been stuck in situations that we didn’t know how to handle best. Hell, they even made a Twix commercial about it.

Here are 8 situations (guys only) with answers whether you should “Shut Up,” or “Squeal.”

1. A friend is really bad at his job, and it’s obvious he’ll be fired.
Man Code: SQUEAL. A good friend would tell him, “Dude, I’m hearing things. You’d better talk to the boss.” An okay guy deserves a heads-up.

2. When drinking, your buddy turns into a jerk.
Man Code: SHUT UP, at first. The next time he hits his limit, leave. He’ll give you crap after he sobers up, and you can give him crap right back.

3. You’re undercharged $100 for something.
Man Code: SQUEAL. Come on, you’re just asking to be hit by a karma delivery truck.

4. Your buddy is financially irresponsible, in debt, and not saving for retirement.
Man Code: SHUT UP. No man should ever speak to another about how he spends his money. If your bud asks to borrow 10 grand, however, the gloves come off.

5. A coworker’s padding his expenses.
Man Code: SHUT UP. He’s a sleaze, sure. But it’s his sleazy business, and if you turn in clean receipts, some bean counter will eventually compare and catch on. Smile then.

6. In a beer-fueled act of lunacy, you kiss your best friend’s girl.
Man Code: SHUT UP. Except to apologize to her and pray it’s never discussed again.

7. You hook up two friends. She’s into it, but he’s cheating on her.
Man Code: SQUEAL, to him. “She’s my friend, just like you are,” you should say. “If you can’t do right by her, cut her loose.”

8. The guy at the body shop offers to up his estimate for the insurance company and says you can split the difference.
Man Code: SQUEAL. Say, “No, thanks. Let’s play it straight up.” The karma delivery truck hits newly repaired cars, too.

It’s pretty clear, us guys get away with a ton of crap. We can sit on a couch, sans t-shirt, drinking a beer, yelling incessantly at a football game, and it’s considered “normal.” We can usually walk up to a tree, drop trough, and urinate without a second notice. But, there are definitely things we as men should avoid. Here 19 things all men should put on their “To-Don’t” list.

#1. Check your BlackBerry in bed.
To a woman, that’s like having a threesome with your boss.

#2. Ask for a kiss.
Her eyes will say yes or no, and nothing kills the mood like asking for a translation.

#3. Wear low-rise jeans.
So what if David Beckham flashes his hash in every other men’s magazine? It’s important to have some sack, not show it.

#4. Mess with another man’s automobile.
I don’t care if he stole your wife, your job, and your dog. It’s blashemy.

#5. Send an angry e-mail.
Have the huevos to pick up the phone or, better yet, meet face-to-face. Fireworks aren’t just for Independence Day.

#6. Dismiss a woman who shows any interest in watching baseball with you.
She wants you bad.

#7. Snoop through her e-mail, closets, or medicine chest.
There’s probably nothing there you need to worry about. But rest assured, you’ll find something you don’t want to see.

#8. Keep a home-run ball hit by the opposing team.
Or one hit by any player on the juice. I don’t care if it’s worth millions. Throw it back or you’re a traitor.

#9. Forget an undershirt.
Go ahead, let ‘em see you sweat. Just don’t let ‘em see sweat creeping out from your underarms like dark, foreboding tunnels to your moistened soul.

#10. Four words: inner-thigh adductor machine.
It might be a tough-to-reach muscle group, but there’s never been a better way to strain your self-esteem.

#11. Talk politics or religion with new friends.
And if you consider sports one of the two, leave that off the table as well.

#12. Talk salary.
The more you make, the easier it is to cheapen your image.

#13. Have that extra drink.
You know, the one that takes you from hilarious to hyena. Always respect your tipping point.

#14. DIY plumbing.
You think it looks easy. Then your house falls down. Water, like Hulk Hogan’s wife, is not to be flirted with.

#15. Leer.
Sure, her buttons are quivering to rein in her pendulous bosoms. Sure, it looks “cold in here.” And sure, each giggle causes her chest to sway suggestively. But “pervert” isn’t a label you can just peel off.

#16. Argue with a cop.
You were caught. Own up. Accept defeat. The only thing you win in that battle is a humid cell and a roommate nicknamed Stabby.

#17. Hang anything – your cellphone, your keys – on your belt.
You’ll never get laid again. True story.

#18. Pluck your brows.
It’s okay to groom. It’s okay to like a woman who grooms. It’s not okay to groom like a woman.

#19. Go tanning.
Forget skin cancer. Being trapped between heating elements is for cheese.

Did I miss a “To-Don’t” that should be added to this list? I’m sure there are more, and if you know any, leave them in the comments!
