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.

Flat Rate

Flat rate is a method of payment used by auto manufactures, dealerships and independent repair facilities whereby every repair has an assigned time value. Better technicians prefer to be paid this way as it rewards experience and speed. Also commonly known as book time.

Wow Pete did I just see you replace that engine in just a few hours? Sure did Joe. I beat the shit out of "Flat Rate" by doing it in 5 hours! My next paycheck is gonna be huge!
