A phrase coined by Elaine on the TV show "Seinfeld." Refers to Elaine's favorite kind of birth control that was ultimately taken off the market. Elaine bought all the remaining stock she could get her hands on and then hoarded her stash of sponges. She defined her dates as being "sponge-worthy" or not i.e. if they had sex. If he was worth using one of her hoarded sponges!

When your so pissed off from losing multiple amount of games that you play worse and worse till your so pissed you begin leaning over your keyboard screaming over every little mistake you make and complaining about gaming imbalances

(Common in Starcraft II)

from "Seinfeld": an attractive man, worthy of being a woman's next sex partner, particularly when her preferred method of birth control is the contraceptive sponge, and her stockpile of sponges is limited (since the only manufacturer had discontinued production).

Worth fucking in a time of scarcity; from a Seinfeld skit about the discontinued sale of contraceptive sponges.

someone you would totally have sex with.
