boo hammer

The act of ruining someone else's good time. A total buzz kill.
I was all excited about going out for tacos and then Mike came in and dropped his boo hammer...now we're having sushi.

I'm dropping the boo hammer; the party's over.

Quit being such a boo hammer.

Boo-Pig

An unattractive, fatty-bo-batty girlfriend whose desperate need for love and affection blinds her to the true nature of her secondary status. Boo-pigs are good for bizarre and often painful sex to which one's actual boo would never submit. (Both a noun and adjective.)
After Denise left, I called over Tammy and pissed all over her boo-pig face.

boo-yaa

n. (1) During the 80's and 90's, boo-yaa was popular urban slang for a shotgun, or the sound a shotgun makes when fired. Similar to bada-bing
(2) Due to the popularity of gang culture in urban areas, the shotgun imitation sound was embraced by urban culture and often used to the point where it came to mean other things, such as "Hell yeah!" "Right on!" "In yer face!" or simply "Yeaahh!"
(3)In the late 90's and early 00's, boo-yaa was embraced by mainstream white culture, and the shotgun meaning was completely dropped and forgotten. In the mainstream white culture, boo-yaa simply became a yell of exuberance or joy.
(4) The Boo-Yaa T.R.I.B.E are an experimental Los Angeles gangsta/alternative rap group. They named themselves after the urban slang word for a shotgun or the sound a shotgun makes when fired.
(1) The cat pulled out his gat, and boo-yaa! the other nigga was dead. Then he dropped his boo-yaa and ran like fuck.
(2)Boo-yaa, sucka, you got knocked straight out!
(3)Boo-yaa! Yaaay!! I won the game!
(4)The Boo-Yaa T.R.I.B.E are one sick rap group.
