Sleeper booty

A girls butt that doesn't look good in most types of pants , however when the pants come off , or she wears tight yoga pants and similar pants her ass looks great. Like a sleeper agent Activates by a trigger for their mission, allowing them to transition from their "dormant" state to active. The sleeper booty is dormant until it she Activates it by making a choice to let those beautiful cheeks be seen in all their glory.

Sleeper

A part of the cab or an attachment to a semi-truck often used for loads that travel a far distance. The sleeper contains one or two beds that are of decent comfort (in my opinion) especially with blankets. For two-person trucks, there is usually a bunk bed so that you and your passenger can sleep.

Driver: "We only have an hour left, we need to go to the sleeper"
Passenger: "Ok."

Sleeper

I term used by serious car guys to describe a vehicle that is plain and boring looking but is really fast as shit. Basically it’s a car designed to look like something your grandmother would drive but it has a big bad ass 5.0L V8 engine under the hood.

That 5.0 Hyundai Genesis R-Spec 4-door sedan is a straight up sleeper. It has 440 hp and my grandma loves driving it because it’s easy to drive.
