Ghost nap 

When you sit in the back of class and lay your head down with a hoodie over your head and go to sleep,

Mary: Who's that sleeping back there in the blue hoodie?
Bill: That's just Richard taking a Ghost Nap after pulling an all-nighter.

When you sit in the back of class and sleep with a hoodie on, obscuring your identity from attentive teachers and peers

Mary: Who's that sleeping back there?

Ghost Nappa 

From the online hit "Dragonball Z Abridged" created by Team Four Star, Ghost Nappa is the awesomely hilarious poltergeist Nappa becomes after Vegeta kills him in Episode 9.
Nappa was quickly established as everyone's favorite character, and to keep him in the show, Team Four Star invented Ghost Nappa. Those clever bastards.

"When there's something strange, in the neighborhood, guess who it is? GHOST NAPPA!"

Nappa's most awesome and powerful form, greater than vegito and SSJ4 Gogeta, can torment Vegeta, identify Pokemon and sing the theme song for a popular 80's movie

"Ve-ge-ge-ge-ge-ta ge-ge-ge-ge-ge-ta ge-ge-ge-ge-geta GHOST NAPPA!!!"
