chubby punchin' is jerkin off with a semi-erect penis
Dave - 'what did you get up to last night mate?'
Steve - 'the Mrs. came round mine and we watched a film'
Dave - 'Nice, what film?'
Steve - 'Fuck knows I drank too many beers and couldn't get it up so so the Mrs. fell asleep, needless to say I ended up chubby punchin' myself to sleep.'
This happens when you are wearing tight jeans while riding through a pasture (or off-road) in a truck. Next thing you know, you got a full on chubby because your jeans are rubbing on your penis. This is caused by the truck rocking back and forth due to the rough terrain.
"Damnit, these jeans are too tight, now I have a pasture chubby."
her: "Babe, why is your penis hard?"
you: "It's not hard, I got a pasture chubby!"
