A bitty is an over intoxicated female who frequently roams the trashiest bars and dance clubs in your city. Native to Michigan, bitties tend to flaunt their plump bodies on top of speakers, attempt to pole dance on stage, try to make it rain, and are often seen drinking a Sex on the Beach. If you see a bitty on the street, she will most likely come up to you and sound really loud and obnoxious, but do not be scared because the subtle use of sarcasm, or a quote from Patch Adams, will forever render the bitty confused.
