A bubble of feminine ejaculate that has been mixed with other feminine ejaculate from a large orgy, and is infested with the AIDS virus. Often used as a derogatory term when having an insult contest, often times it ends the competition.
A droplet of human jizzness that is filled with air (you know, similar to a ballon), and apparently filled with urine due to failure of the prostate gland.
1) Holy shit dude, look at that piss infested cum bubble coming out of your incredibly nasty penis!
2) Dude, you're just so fucking retarded that I have to call you a piss infested cum bubble.
Female: The movement of a fart as you are sitting or lying down and your legs are closed. The gas bubble moves between past your taint through your labia major and dissipates near the clitoris.
Males: The movement of a fart past the taint to the scrotum, essentially trapped methane. Normally a silent fart.
While lying on my back in bed, I farted a felt a bubble up, my boyfriend didn't notice.
