J-Jitters 

Involuntary jittering movements brought on after inhaling, ingesting (sometimes even just breathing) something. This acts to heighten the enjoyment of said 'something', but can often lead to a life of being laughed at brought on by the comical nature in which it is performed.

Nat: *takes a sip of green tea*
Chad: *also takes a sip.. then J-Jitters*
Nat: GRRRR.... *punch*

J-Town Jitter

A dance done by white people who cannot dance, usually with a wild flailing of the arms and ignoring the beat of the song.

Bernie: Man did you see whitey dance?
Cory: Yeah man he can't dance, he was just doing that J-Town Jitter.
Bernie: ...Boy needs some lessons.
Cory: ...You aint any better.
Bernie: Do something about it.
