nkbj Share definition Flag When a man and a woman meet for the first time, and the woman tries to kiss the man but he kindly refuses but instead asks and receives a blow job instead. Simply put a no kiss blow job. That sloppy bitch tried to kiss me, but i shrugged her off and she threw me an nkbj instead. nkbj by Jcayse May 5, 2008 0 0 Get merch Get the nkbj mug.
