To put a dip in your top lip, as oppossed to the more widely used bottom lip.

My bottom lip was tore up, so I had to turn to top shelfing it today.

Top Shelfing 

The act of defecating in someone's finest bottle of liquor. A homage to the classic Upper Decker.

Carl was being a douche at the party, so I gave him a good old fashioned top shelfing.

Top-shelfing 

The sport of taking off the porcelain lid of the toilet tank and pooping in the tank of the toilet, thus causing the toilet's owner many days of dirty flushing and unexplained stench.

Top-shelfing

Example 1:
"Dude, I heard you got fired last week...sorry to hear that."
"That's OK man, I top-shelfed them before I left."

Example 2:
"Damn, Jimmy your apartment stinks!"
"Did Sarah top-shelf you when you broke up with her?"

top shelfing it 

Taking a dump on the closed lid of a toilet. Usually performed in someone else's dorm or barracks.

You go into a toilet stall, close the door, put the seat and the lid down, and poop on the lid. This is called top shelfing it. Then you go to another stall and take care of the clean up work. Wash your hands, and sneak out of the bathroom unnoticed. Works best in the middle of the night.

Top-shelving 

When you pop a dip dipping tobacco in your upper lip.

His lower tray was raw so he embraced top-shelving a beaver pinch.
