A tool used to ground up marijuana so it may be rolled. Usually a coffeegrinder is used to do this.

Short for ultimate bias. Typically used by fangirls and fanboys to describe their favourite celebrity amongst the many that they are fans of.

a bud buster is actually a coffee grinder, but put to good use. Grab some marijauna, chuck it in the grinder, give it some power, and voila, freshly ground buds(easy for rolling). I bet Proctor & Gamble would never have thought their coffee grinder would be used for busting buds(hence the term)!
