Backside Creep 180

When you are walking down a road approaching a very hot chick and want to know if her ass is as hot as her face. As soon as you walk past her you turn a full 180 degrees in order to creep on her ass.

Dude 1: Did you see how hot that chick was?
Dude 2: Yeah man, as soon as I got past her I stuck a perfect backside creep 180 to get a look.
Dude 1: And...?
Dude 2: The view was sensational!

Backseat Baker

An idle person who will gladly yell instructions to you while you are busy baking a cake. Not to be confounded with the backstreet baker who, in this case, would be cooking meth.

"Bitch can't you see I can bake my own motherfucking cake; don't be such a backseat baker!"
