Words you can keep

sleeper hit 

Generally any type of media that is marketed as under the radar, yet is of quality to have been a top tier marketing tool.
"That game is definately a sleeper hit, easily worth my twenty dollars!"

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.

Sleeper Build

A physique that is not appealing to the naked eye until it is flexed or uncovered, normally someone that looks small but big when flexing.

Ricer-Sleeper 

A vehicle, usually an import tuner, that is heavily modified under the hood (built engine, forced induction etc), capable of being faster than most other modified cars, however has non-performance damaging flamboyant cosmetic modifications (stickers, a large spoiler, hood/roof scoops, large obnoxious muffler).

A ricer-sleeper accomplishes being a sleeper (a car that does not look fast but really is) by appearing to be a ricer (a car that is modified to look cool and fast but in reality is not).
Guy 1: OMG! LOOK AT THAT RICER! Looks like he took the Fast and Furious trend too far...

Guy 2: LAWL YES, i bet it's a stock, base model, automatic!

Guy 3: That thing just beat my 300HP Nissan 5 minutes ago...

Guy1: OMGAWD its a sleeper??

Guy2: OH SHIZ! It's a ricer-sleeper.

no-sleeper 

A no-sleeper is the corporate equivalent to a no-hitter - a presentation in which nobody dozes off.
Kurt had a no-sleeper going until he got to the financing options slides - then he lost it. Badly.

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Acronym, meaning Too Long Didn't Understand
Similar to TLDR
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.

Me: Woah! TLDU!
