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 cell

When a based and red-pilled gamer has to control their power level, so that the unwashed masses don't start noticing anything.

SUSAN: Hey Mark, what do you think of BLM? They really help amplify the voices within marginalised communities, don't they?

MARK (Sleeper cell): Yes, love em!
