To be suddenly and uncontrollably happy/excited. Such as when you are told good news and you get such a surge of happy emotions that you feel like making a sudden, loud, squawking noise.
Anyone who is high on meth and attempting to project (by project i mean clean, organize, alphabetize, disassemble, attempt to reassemble, categorize or just plain destroy in an effort to understand how it works or make it better) on the nearest computer, cell phone, disorganized bedroom or closet, bicycle, car interior or exterior, bathroom, squack box (box filled with random crap said tweeker has picked up during his/her many useless hours spent high) or a garage.
Holy shit Martha did you see how squacked out that guy was? I think that was an old 8 track he had disassembled on his front lawn.
