Yo, listen up boys. These are the unspoken rules you need to know if you want to keep it real.
- Never go after a girl your friend is already going after. That's just low-down dirty, and you'll lose all respect.
- Never shake a hand sitting down. Stand up and show some respect, dude.
- Protect who is behind you, and respect who is beside you. You're a team, and you gotta have each other's backs.
- Never eat the last piece of something you didn't buy. Show some manners and offer to grab the next round.
- Don't throw your friend under the bus to impress someone. Loyalty is everything, and if you ain't got that, you ain't got nothing.
- Never insult the cooking when you are the guest. Show some gratitude and enjoy the meal.
- Don't use the urinal next to an occupied one. Keep some personal space, man.
- Don't take out your phone during a conversation. Show some interest and give the person your full attention.
- Never take credit for work you didn't do. Honesty is the best policy, and you'll earn more respect in the long run.
- Listen, nod, and most of all make eye contact. Show that you're paying attention and engaged in the conversation.
- Don't make fun of your friend in front of his kids. Show some respect for the little ones.
- Never let emotions overpower you. Keep a cool head and think things through.
- Never beg for a relationship. If it's meant to be, it will happen naturally.
- Dress well no matter what the occasion. Show some pride in your appearance.
- If you aren't invited, don't ask to go. Respect the boundaries and invite.
So, there you have it, boys. Follow these rules and you'll be on your way to being a stand-up dude. Remember, respect is key, and manners never go out of style.
