JASS
A combination of the word Jack... and ass, forming a quicker faster way of saying "jackass". Origanated from a kid who was confused and didnt know what word he should say.  he was going to say ass at first, but he also wanted to saY jackass.    And so jass was formed.
you are a jass. :(

my god, stop being a jass.

you fucking jass!
