From the episode "Laundry" from Jake and Amir. When two guys hang out and start crying. Amir does this often around Jake for no apparent reason.
Amir - Look at us crying up here like a bunch of ninnies. Heh, everybody turn back, don't look at us. Two dudes, two grown men, just sharing a beef.
Jake - What's a beef?
Amir - We're beefing right now!
Jake - No we're not.

What a great word, "beefed". Uncle Jimmy was beefin' it up at the club last night and everyone was waling away from him.

It's when you need two gats to go to sleep, it's when your mom ain't safe up in the streets, it's when I see you, guaranteed to be in ICU, it's when you make your enemies start your jeep, it's when you role no less then 30 deep, it's when I see you, guaranteed to be in ICU
Ask yourself, do you know what beef is?
