A "likeout" is when you give a thumbs up to everything on someone's Facebook profile by using the the "Like" function. The likeout victim receives numerous notifications. The word is derived from "psychout" due to the fact that the victim does not know if their friend genuinely likes everything on the profile or not. (Usually they don't.)
An expression used to describe anything that is very, very slow. (since a line of people waiting to get out of Hell would logically not move at all!)
Cell phone call:
Guy: Hi, I'm going to be a bit late.
Girl: Why?
Guy: I'm at the grocery store and this line is slower than the line out of hell!
Girl: Well, get here when you can!
