look up any word, like fob dot:
to steal or "jack" one's "swagga" or own unique style or personality that makes them hotter than your boring ass. Often occurs when one is jealous of a much sexier, popular, loved, fun & entertaining individual.
You design an original thing thats all your own & expresses part of who you are. Someone jacks that, claims it is theirs, & looks like a dumbass swagga jacka cause everyone knows it was yours first.

aka: You can jock my shit, but u can't rock my shit.
