English for Partygoers

Often times on the subway ride home, I will see people studying English.  Usually, it's just strait forward English lessons, or sometimes on specific subjects such as economics or biology.  However, today I saw something completely different.  There was an older business man in a nice suit sitting next to me, studying a small English book.  It had conversations in English and then translated to Korean as well.  Let me give you some examples of the things this businessman was learning:

A: Hey man, let's do a lap around the bar before we get some drinks.  We need to mack us some shorties.

B: No, I already met this beautiful young lady.  She's gonna be my boo!

A: Dude, she doesn't even like you.

A: Yo, girl.  This party is jammin'.   How bout you give me your digits?

B: No, I don't give me number to strangers.

A: Dude, Tom is totally trippin'.  

B. Yeah, he took way too much acid.  He has to be forced to go to a doctor.

A: Yo man, you got any weed?

B: Yeah you got the cash?

A: Of course. I'm gonna be rollin' in this club all night!

A: I saw you flip me the bird from across the room.  Why you got beef with me?

B: Chill out man, it was a mistake.  I don't got beef with you.

I wish I could make stuff up that was this good.  But unfortunately, these are real examples from the businessman's book.  I'd like to see him try to use some of those.
