Get the grindingmug. A form of the most horny dancing imaginable.  Guys looking for ass will grind profusely with random girls in order to pursuade them to come home and get some bun action.  Involves pushing the male genitalia up the ass of the female.
At the club last nite, I got hammered and was grinding with every girl in there...so much, that my package was sore the next day

Get the grindmug. A repetitive task usually involved in a Massively Multiplayer Online Role playing game (MMORPG) where a character's skill's are based entirely on killing monsters to gain strengths or levels. In most MMORPGs, there is no skill from the player involved, so anyone who plays 20 hours a day of grinding will be stronger than a player who does not. MMORPGs become a game genre filled with those who are too slow to play First-Person Shooters (FPS) or too dumb to play Real Time Strategy (RTS) but want to brag and be 1337 g4m3r so they play 20 hours a day and boast to "n00bs"

me_is_noob: wow you are so uber 1337! You must be so good at this!
