booty-bumping

(verb) The anal ingestion of a drug, administered with a syringe. The method is nearly as effective and as fast as intravenous method. As with all things there can be some unpleasant side effects depending on what chemical/drug is being injected.

Stevie could not hit a vein for shit earlier. I think he did it that on purpose because in short order after a few attempts, the fagget-singer broke the needle tip off his rig, raised up in the seat, cause I was driving when he did it, and then he worked his hands behind him and gave me a first hand demonstration of booty-bumping.

e-bay bumping

Manipulating the price of an e-bay auction by simply placing a bid with no intention to buy, but rather to increase price more rapidly for the seller. Should the bumper be the winner of the auction, they will be transafered the money by the seller after payment, and give him back his goods.

Sometimes this occurs when the bumper simply wants to annoy others by pushing the price to ridiculous amounts near the end of the auction so desperate bidders place higher bids. These people also enjoy pestering the seller with questions about thier sexuality and underwear hygeine.

Spotting e-bay bumping is quite hard, since many n00bs unintentionally push the price up by placing consequtive increasing amounts for the same item within minutes.

If you notice that an item has a bidder who has placed multiple bids for an item, check thier feedback. If you notice this person has bought several items over a long period of time from the current seller, you have probably uncovered a scam, and should report it.

dumper bumping

Dirty anal sex. It was first pioneered by the Gap Tooth Pirate, Cromer. Before ejaculation, the man pulls out and cums on the girl's face, because "she knew it was coming".

Cromer and Tiffany were dumper bumping in the locked room. I knew because of the grunts of pain from Tiffany and the stink of bunghole and sweat.
