A euphemism for male masturbation.
I'm sure that episode of Golden Girls got you pretty aroused, why don't you go lock yourself in the HR conference room and dance with your monkey for a while?
The sexual act of achieving orgasm by using a rotting pumpkin as a makeshift male masturbatory aid.
I was taking out the trash and I caught my roommate giving himself a sloppy pumpkin with the jack-o-lanterns we threw out a few weeks ago. Ugh, it's almost Christmas, it was nasty.
