A free swimming infant form of sessile aquatic life. So called because of its whiplike protrusions which vaguely resemble the snakes that formed Medusa's hair.
"After self-fertilization, a single celled medusae is formed. This form is free to swim around, until it finds a suitable location, whereupon it will attach itself permanently and develop in to the sessile polyp form."
A trip to a grocery store, convenience store, or gas station for the sole purpose of buying an excessive amount of junk food and sugary drinks, usually with friends. A chud run often happens late at night and ends with everyone involved hating themselves afterwards.
