NAPJERK 

(nap' jurk) n. The sudden convulsion of the body just as one is about to doze off.

Sometimes at the moment I reach deep sleep I have this napjerk of me walking down a street and suddenly I trip over a crack in the sidewalk.

Napperkin

A formal handkerchief first mentioned in the poem The Man He Killed by Thomas Hardy.

Right many a napperkin!

Nap jerk 

When your head drops suddenly from dozing off

I had a mean nap jerk during math class
