Someone who is using methamphetamines and is skitzing or behaving obsessively about doing something is geeked out. Someone spending hours to accomplish a meaningless task: trying to fix and unbroken item, playing games for obscene amounts of time, picking at skin for no reason, deciding to organize an unruley amount of items by color-shape-size-alphabetically-and numerically when it does not freaking matter. All done in consecutive amounts of time-without breaks & without blinking!
MAN 1: "You mean you skitzed last night and have been organizing all 5,000 baseball cards according to the third initial in the players last name? Man your geeked out!"
MAN 2: no reply because focused too hard on pointless task & did not even hear MAN 1 talk.
