sleeper award

Someone or something that after a long period of time, reaches a higher level of potential, or success.

I was a very shy and meek kid in high school, but when I reached my 20's, I came out of my shell and became very outgoing. My friends told me that I get the sleeper award for how social I've become.

sleeper brony

Someone who is not currently a brony, but would become one after watching My Little Pony. Calling someone a sleeper brony would be based only on a

personal assumption, given that her/she hasn't watched the show yet. This term is comparable to "sleeper agent", in that both are activated through

an external medium, and both are completely unaware of their hidden identity.

Non-Brony: I think MLP is the stupidest, girliest thing on the planet.

Brony: Have you watched the show?

Non-Brony: No.

Brony: Then you should give it a shot. Who knows, maybe you're a sleeper brony.

Dead Sleeper

Far worse than a heavy sleeper. You could slap them and they would never wake up.

You would have to be a dead sleeper to not wake up from that...
