When someone cannot successfully spit into a gaping asshole.
Michele was trying to spit in Jeffrey's gaping asshole and he she missed and spat right dab in the middle of his taint completely missing his gaping asshole. Michele is such a boo whore.

Get the Boo Whore mug.
The next fad of todays generation. While in the 60's they had cannabis, in the 00's we have Boo Whore.

It was first coined in the hit movie Mean Girls, although unfortunately not by Lindsay Lohan as we all wished. This does not ruin the fun and frolic of the saying however, and nowadays it is seen as a good gesture to use this phrase whenever you see fit.
1) Boo Whore! - as a greeting
2) Boo Whore! - as a threat
3) Boo Whore... - as a way of expressing ones tears
4) Boo Whore! - as a way of shooing off unwanted ethnics
5) Boo whore? - as a way of questioning God almighty

Get the boo, you whore mug.
Coined from the hit movie "Mean Girls" by the excellent actress Rachel McAdams. It can mean many things, either friendly or non. Mostly used as a greeting, or as a burn, bitch. It's a flexible saying, but be sure you're friendly before using in a joking manner, it could be offensive as well.
Jeanean: "Hey Kylie!"
Kylie: "Boo you whore! what are you up to girl?"
+++
Geneva: "I'm so upset! My boyfriend David broke up with me!"
Olivia: "Boo, you whore-- get over it!"
+++
Barbie Barbara: "Damn, I'm hot in my A&F jeans."
Emo Emily: "Boo, you fucking whore! Get over yourself, cake face!"
