Noun. A plastic bag (usually from a grocery store, bodega or other ghetto-mart) that has been inflated and borne aloft by the wind, giving it a jellyfish like appearance. Common in neighborhoods where littering is acceptable but walking on a sidewalk isn't.

Oliver is a very nice guy. He usually has blonde hair and blue or green eyes. He is a flirt with all the girls but usually has someone special on his mind.
friend 1: He’s pretty hot

friend 1: I’ll change that...
