Gumping is when you perform "sexual activities" to yourself, while licking a toilet seat in a public place!
Steve broke into a tramps den and robbed his toilet seat for a good old gumping session, then returned to give the tramp a blowie for his can of beer ;)

The act of doing/saying something really stupid, and making yourself look special needs to everyone around you.
"When that kid stubbed his toe and threw a temper tantrum, he was really gumping it."
"You're really gumping it with all of your Poppy Playtime jokes."

"I need to confess a sin, Father. I worked at a grocery store in my teenage years, I won't get specific. There was this one girl-- are you familiar with the term 'gumping it' --so while it's an ethical conundrum, it's not fucking a retarded person if you were to sleep with 'em. This will come important later in the story..."
