Lads Rule
Lads rule happens when only a few guys are still awake at the end of a night. You get all the leftover beers. If someone won't give you theirs, just say lads rule and they'll be too scared to argue.
I'm not giving you my beer.
Lads rule. You're not even a real man.
You'll be the talk of the town if you don't give me that beer.
