smiling caboose

When you take your first finger and middle finger and twist them together like your crossing your fingers, but you straighten them (still crossed) and you stick them in your rectum and uncross them. Enjoy

Last night we were doing in and he gave me a smiling caboose.

chessie smile

A breed of dog called a Chesapeake bay retriever (or a chessie) is known for their "smile" they make when they get excited. May be confused with growling, but the smile is not a form of aggression.

When the dog named Hudson's owner came home, he had a chessie smile because he missed her

flat smile

The passive aggressive look you get from your wife when you haven’t done something or, asked for sex. It’s characterised by a straight mouth, with mildly pursed lips, a raised yet furrowed brow, and rarely any verbal communication.

Oh man, she’s given me the flat smile. I’m cooked.
