St. F has a picnic on Sunday, who makes their booyah?
Derivative of the simple (Mandarin specifically) phrase "Bu yao," which directly translates to "don't want."
Synonymical slang phrases may include: "In your face," "Suck it," or you could even try "Boom, that just happened."
"Take that biotch," "what else you gotz," and "eat uh d" are also in the same vein.
Sometimes pronounced boolyah depending on vernacular interpretation, and often spelled booya.
Note: If actually spoken in Mandarin, and understood without slang, it would mean that you personally didn't want any of what's currently being offered. Ex: "Yao bu yao __blank__?" -> "Do you want or not want __blank__?" Answer: "Bu yao" -> "Don't want."
