an ambiguous slang phrase used in the "ghettos", which can only be uttered by a guy that is a member of the Bloods, Crypts, Warriors, and Newsies, a kid from Westchester County that masturbates 30 times a day, or a niggardly Negro. While varying between contexts, the phrase commonly means "double stuf that", "dry swallowing almost anything", "spidermaning that shit", "Shanghaiing", "Erkin' it up", "fucking defenestrate that bitch". When three-piece is used singularly, it refers to womens of the women-kind that are as loose as my rhymes are smooth.
"I got this chem paper due tomorrow, no homo. I bests three piece that shit."
