Generally any type of media that is marketed as under the radar, yet is of quality to have been a top tier marketing tool.

Sober Sleepover 

The point in a relationship when you are officially dating someone even if you haven't had the 'are we dating' conversation. Several drunken sleepovers may have occured at this point but once a Tuesday rolls around, you watch a movie together, and have a alcohol free sleepover...you are dating.

Ben: How are things with Julie? You've been hanging out a ton. Are you all dating yet?
Rich: Good, but no way we've only hung out 3 or 4 times.
Ben: Have you had a sober sleepover?
Rich: Um...yeah.
Ben: Dude, you're totally dating.

sleeper car 

A car that has high performance but intentionally looks to be ordinary or even beat up. The polar opposite of a rice burner.

Did you see that sleeper car waste the Ferrari yesterday?

Sleeper Peeper 

A boner that arises at the moment when you are close to falling asleep, but becomes so uncomfortable that you must push back your sleep and instead focus on getting the boner flaccid. Typically one rids themselves of this type of erection by removing underwear or whatever they were sleeping in, and then not letting the peeper touch anywhere else, as that may keep the boner going. It may take awhile.

Dude 1: Yo man I got no sleep last night.
Dude 2: Damn that sucks. What happened?
Dude 1: Sleeper peeper bro. Shit didn't go away for hours.
Dude 2: I feel you dude.
