Bob: WTF!?
Mike: Nope, that was Jeff.

When you got a cute, little hoe and a pineapple. You and the homies cut the pineapple into slices and take it in turns to put your dick through a slice and fuck that bitch’s ass. Last homie to fuck her has to eat every slice of the pineapple.

Hipster 1: "Kay, yo, I just got the new All Time Low CD!"
Hipster 2: "Groovy Train!"
Hipster 3: "Shut up! You guys are flippin' stupid!"
Hipster 2: "Groovy Train!"

when you form a chat-like conversation over the email with one or more people by simply replying again and again to the same message. Each reply is usually a question or something thought-provoking, prompting the other person to respond as well. They can get pretty long.
"dude, here they don't allow chatting on the school computers, so i usually get by talking to her with these huge-ass email trains each morning."
