knob bobbin' 

A man or woman who makes a hobby out of sucking a man's dick.

Dude, Jeff always goes out every Friday night to suck-off as many guys as he can find in the back of that new club called "The Raw Sausage." I think it's time for all of us to go out and get unzipped. We have enough "raw sausage" between us to keep him knob bobbin' for hours. We'll send him home with a belly fully of our sause.

Knob Blobbin 

In reference to the appearance of the "blobfish," any person, usually overweight, completely lubes up their body and places a dildo in place of their nose. This act is typically for fun.

"Woah, look at Felix, he's Knob Blobbin right now!"

"Sam, why do you have 700 gallons of lube?"
"Cause I'm Knob Blobbin myself for hours after you leave."

"Look at me ma,' I'm Knob Blobbin with no hands!"

Knobgobbing 

The act of two or more women ducking on the head of a man's penis at the same time, as though they were fighting to be the one sucking in the head, but really they are working in unison to both have their mouths sucking on the head of the penis at the same time.

Look at that lucky guy over there. The three hot chicks are knobgobbing his cock.
