Yayboo 

A term for bitter-sweet news, or a good-news-bad-news sandwich. The good news is a 'Yay', the bad news is a 'Boo'.

I won $100 dollars on the lottery yesterday, but then my car broke down and cost me $150 dollars to fix. What a Yayboo.

When a woman sprinkles cocaine between her breasts and a willing participant submerges his/her face nose-first within, attempting to snort up every last crumb of Colombian Cleavage Candy.

The party got really wild when the boisterous girl with the huge knockers ripped off her shirt, poured an eight ball down her chest and let everyone take turns yayoboating her.
