rats are like mice but tricky and not as nice. they like running around especially if there is a treat or reward in the corner sort of like being in a maze for a human.they are smart and will run out of their holes to steal or catch food then run back.if you see a rat just give it some food or cheese and wave goodbye
"did you see that rat?!"

"yea it took the cheese and didn't even get caught in the trap"

A slang term for female breasts that makes little sense which most likely originated from the working-class vernacular. The word 'rats' is short for 'ratty-tat tats', a phrase itself which makes little sense.
Check out the rats on that pregnant chick.
