Abbreviation for "Western Business Attire". Commonly used by MUN officers who are too lazy to type out "western business attire" and instead just write "wba", causing many confused freshmen to go to urban dictionary to find out what "wba" is only to find out that nobody else knows either.
Person A: "Come to the MUNmock tonight with W.B.A. please!!"
Person B: Western Band Association...?
(n.)
"Wanna Be Hipster"
A person who likes "hipster" things but only because they are known as such. Tries to hard to get a look that's not trying at all. Enjoys things such as Starbucks, thick square frame glasses, Instagram, woolen scarves, and Toms.
I know a W.B.H. who just heard about the Starbucks Keurig combination.
Look at that girl in the "vintage" clothing wearing Toms. What a W.B.H.
