Knowmb : noun : [nom] or [k-nom]
Definition: A knowledge bomb.
It's when someone throws out some random fact or stat or smartness thingamajig that just blows your mind. Well your mind was blown because you got hit with a knowledge bomb, or a knowmb, as I heard a fourteen-year-old kid say the other day at a family member's scouting function. Amazing stuff, those knowmbs that kids are throwing around these days. Or so I hear.
