Solitary past-time or activity of walking/jogging aimlessly in pursuit of one's destiny or future.
I don't feel like getting drunk again, I'm going gumping instead.
Pre-maturely blowing your load, like Forrest did with Jenny.
Mark gumps every time he gets a lap dance.
The act of being tied up by someone and them then unleashing their gimp on you for a serious humping.
we picked up some boys and took em home and gumped em
I'm gonna give that slut a cruel gumping
Is everything and is everywhere but no one can find out what it is.
Hey man she’s kinda hot, yeah I think I’m gonna take her to the Gump Gump.
Mom: What do you want for dinner?
Me: Gump Gump
You best change that attitude before I send Gump Gump on you!
So, 'gumping it' is when someone is not quite retarded, but they're like just on that line.
"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..."
When a person is not quite retard yet they are on the line.
Yeah I fucked that slow chick, but it’s cool since she’s gumping it and not a full retard.
