peenjo bumping

When two men or more engage in Double Penetration Sex in a woman, in the same hole, and their penises rub up against each other. It might as well be considered tummy sticks.

Peenjo Bumping is all the rage in "straight" DP porn these days.

Shadow-bumping

On the IMDB forums, the act of posting a blank response and then deleting it a second later thus intentively bumping the targetted thread and remaining anonymous as the bumper.
Specifically detested because it is a stealth form of necroposting and often used by trolls.

boxOmetal: some idiot just revived that y2k thread
cardboardboy: yes, well done idiot
boxOmetal: wtf?
cardboardboy: saw your name on the most recent post before it was deleted you shadow-bumping idiot
