The fat that hangs over a fat woman's vagina. You can usually find a boosty on a 250+ pounder. Most boosties are formed from eating too much McDonalds hamburgers. The African American boosty is usually formed from eating too much chicken wings, hotdogs & various other grilled meat products. The quickest way to get a boosty is to eat a lot of bologna sandwiches. The boosty is also used by the man during sexual intercourse for satisfying penis pleasure. During the sexual intercourse with the boosty, the woman can experience a strange type of orgasim if the boosty is pounded hard enough. Lesbians also engage in boosty sex by fingering each others boosties. The name for a boosty fart is a "tramabomb".
