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.

flat rat

A condition when hamsters are VERY happy and relaxed with their human friend.

First, they have to trust their human as a personal presence. Then, they have to trust that their human friend isn't going to suddenly become aggressive toward them.
then all you have to do is to pet them on your hand until they become flat.

bro you're hamster is a flat rat
