A large beard, or the act of growing one.
Pronounced Tali-bON for rhyming effect, this versatile, yet offensive-to-some term can be used as an adjective, verb or noun.
Steve (with a brief scan around the room for non-whites): Hey Jim, have you been trimming, or are you still going with the full-on Taliban beard?
Jim (with mischievous giggle): No, I've been full-on Taliban for weeks now, it probably just looks like I lowered the terror alert level on this bad boy because I got a haircut. But it's still a full-on Taliban for now, you betcha.
