A slang phrase referring to 4 prominent odors that one would sense when visiting Indiana University in Bloomington, Indiana (aka B-Town). The smells are as follows: beer, barf, bud, and bagina.
(while walking through the Indiana University campus)
Mike: What is that smell?!
Sam: Oh, that's just the 4 B Smells of B-Town.
