Grinding Pepper 

the act of giving a handjob or imitating a hand job that appears in a twisting repetion of motions.
That resembles the act of grinding pepper, fresh from a pepper grinder.

Dude, I walked into Mike's house, and his dad was sitting on the couch grinding pepper.

pepper grinding 

The art of fellatio, where the hands of the "performer" replicate the motions of a pepper grinder on the recipients organ.

At a party you ask "Has anyone seen Jane?" An answer you get maybe as follows: "Yeah, she was in the bedroom pepper grinding Steve a while ago"

Pepper Grinding 

To pepper grind: The act of removing the top toilet lid and defecating in it. This act is finalized when the next occupant flushes to only realize the faeces of the last occupant has re-flushed back into the bowl, hence pepper grinding

Note: The use of a nearby toilet brush to break the faeces into smaller pieces amplifies the pepper grind effect and will greater startle the next occupant.

"I just pepper ground that mofo. That'll tech him for eating all my strawberry's!"

"don't use that toilet jess, i just pepper-ground in there hoping steve will fall victim"

"don't come in! i'm pepper grinding!"

"can't wait to go to my step dads house, i am going pepper-grind that prick for running over my soccer ball with his lawn mower"
