If a guy friend asks to hang out. Another guy may never back out to hang out with a chick. The only acceptable time to back out is if sex is involved. If no sex is involved, the only way for the guy who backed out to repent is to buy the guy who asked to hang out food, beer, or a full tank of gas. If food, beer, or a full tank of gas is not bought, it is acceptable to shun the guy who backed out for a maximum of 24hrs. But this action is not required. It is also acceptable to give him shit for it. But if the guy who backed out tells you to 'Fuck off', the guy who asked to hang out must cease the shit talking immediately, and never bring it up again.
Example A:
"Bro, you totally ditched me to hang with some girl last night!"
"I know bro, but I scored last night! And she was a straight 10/10"
"BRO NO FUCKING WAY! GOOD SHIT MY GUY!"
Example B:
"Bro, you totally ditched me to hang with some girl last night!"
"I know bro, let's go to the bar. On me. I know the guy code"
"Alright bet. I'll be over in 15 mins."
Example C:
"Bro, you totally ditched me to hang with some girl last night!"
"I know bro, I almost scored last night. But we can hang some other time."
"Sorry man, yesterday was my day off. I can't for another 3 days. And you know the guy code"
