Cum-quick.

JS

Short for Joseph Smith, the founder of the mormon religion. when you call someone Joeseph Smith or JS, you are insulting them for being stupid, dumb, retarded, idiot, etc.

As seen on South Park.

JS

Nerdy engineering students coined this from Jock Strap.
Putting something together shoddily. half-assed, poor construction, held together with tape.....

As in:
"He really JS'ed that together"

Translation:
"That student assembled his project poorly."

JS-sian

An act that is immature, self centered with a lack of empathy, emotionally fragile, avoidant, bears grudges secretly but acts chill, give up easily. Basically an abhorrent behavior with no sense of remorse or responsibility or effort.

Bob spilt his milk but blamed the milk for being liquid.

I told Bob “Stop your JS-sian behavior!”
