County Mice

A subspecies of hood rats, the county mouse is a person who may be found in suburban areas, living the "thug life". County mice have infested most non-urban biomes, especially those not already settled into by their superior, the hood rat. The county mice population can be spotted while popping wheelies in parking lots, waiting at the bus stop, or, when on the move, jaywalking. This wild species will seek mates in "thots" and compete for their attention. They typically communicate in their native calls, and tend to participate in activities of "niggativity"

When the cats are away, the mice will come out and play

When your significant other or parents are away for a few days and you plan with your old trustful friends to meet up.
It usually happens in a tucked away shack in the woods where wild and crazy sexual experiences occur. You smoke weed, sing songs, lots of laughs, massages, spa baths, explore various kinds of sexual pleasure, lots of dirty taboo sex which is so good you're not even allowed to think about it. It can occur between two or more groups of friends, depends on what tickles your fancy.

Sia: 'Having sex with someone you really shouldn't be having sex with can make you reach for the skies faster than Kim Jong-Un's super large heavy nuclear warhead'.
Jocelyn: 'True, when the cats are away, the mice will come out and play that's for sure'.

Miced

To Trey something

He really miced up closing.

The mice are feet up.

Certain death is imminent. Doom is nearby. Taken from Condoleeza Rice's account of a feared biological poisoning that took place during George W. Bush's presidency. While waiting for test results she was told by an assistant "if the mice are feetup" (meaning the mice lying on their backs dead) then they would soon be dead themselves. If the mice were feet down (meaning the mice were up and walking about), then they would live.

"Dude! What's wrong?"

"The mice are feet up. My girlfriend caught me cheating on her."
