Java: derives from the word coffee. coffee comes from the coffee Bean and when consumed can cause people to be hyper.
Jitter: jumpy, nervous, anxious.
When you put these two words together it is an explosive combination.
So if someone is JavaJitter they are: wild, over the top, nervous, anxious, anxiety ridden, hyperactive etc.
That girl is so hot when I'm around her she gives me the JavaJitter's
Every time I see a cop I get the JavaJitter's!
I can't calm down I guess I'm way too JavaJitter!
I'm going to Starbucks to get a triple espresso, I'll be doing the JavaJitter all night long!
