4. OTFL
One of the ways in which one may choose to roll.

A cleverisation of the term ROTFL, which means "rolling on the floor laughing" and the phrase "that's how I roll."
Eve: "What the hell is OTFL?"

Adam: "On the floor, laughing."

Eve: "...?"

Adam: "It's how I roll."

6. ROTFLYSMTCT
rolling on the floor laughing yet somehow manages to continue typing.
When you use this is a conversation, it somehow explains the obvious. Of course it was really funny what the person said, but you're having a conversation and typing. While rolling on the floor. Laughing. WHAT?

Boy 1: ...And then he fell in front his father-in-law, while holding on to his pants that kept sliding down his legs.

Boy 2: ROTFLYSMTCT
