B.D.A. ---> One minute they can't keep their hands off of you, and the next minute they just want to be left alone...

"In a relationship, and it's complicated" Meaning : If you aren't around, I am single...
Acronym for Bus Drivers Ass. The unfortunate condition is caused by many hours behind the wheel of a bus combined with the poor diet of Mc Donalds ingested between runs.
