Rectual Orifice. Combination of Booty
"Yo bro, I need to get up in her boogina. I'm going to go hit that shit."
A term first coined by the gay Afro-American community to describe the most desired point of entry for the gay black male, the anus, unlike the straights who first seek out the vagina. Boogina is a marrying of the two words "booty" and "vagina" just like the Mangina
to describe the aforementioned. However, today the term Boogina is not limited in use by 42nd st. Queens and the like. A recent upswing in ass play among those outside of the gay enclaves, perhaps influenced by various rap songs like E40's "You and Dat Booty," has brought Boogina out from exclusivity and into America's mainsream lexicon.
"If I'm giving up the boogina to Jorge then he's gonna have to tell his parents about me and him. N'uff said."
It is the combination of booty and vagina, or could be taken as the rear view of the vagina and ass at the same time.
It can also refer to a gay males ass.
Gurllll ... don't let him get at your boogina...
