(Verb) To experience the speedy, lifted, euphoric effects of the drug Adderall or generic Adderall. NOT to be confused with the "half-tweaked" or "zombie" state experienced by those who take it too often (marked by indifference, and a strange respiratory effect in some that produces a "Hkkekkuuhehkk" sound upon trying to sleep).
"Dude, I just wrote five pages in a half hour."
"Man, you're tweaking!"
"This is awesome!!"
"Don't turn into a zombie - you'd piss everyone off and make weird 'Hkk' noises.. like someone we know!"
"Yeah, I love tweaking, not half-tweaking!"
