Awkward Coaster 

When you're taken along for an awkward ride when your friend invites you to hangout when he's actually on a date with his girlfriend.

John invites Andrew to hangout with him. Andrew goes to hangout, and all John does the whole time he's with him is he makes out with his bitch, so Andrew is taken on an Awkward Coaster ride.

-If Andrew eventually ditches because it's so damn awkward, and John yells at him, John is a faggot.

Roller Coaster Crazy 

That special kind of crazy, that some women possess, where you can't decide if this relationship is going to be incredibly fun, or if its going to go off the rails and you're going to die horribly.

So after she throat punched our waitress, because she thought the waitress was being too flirty. We had to get out of there before the cops showed up. We got back to my car, where we had sex on the hood. That's when it occurred to me that she might be a little Roller Coaster Crazy
