Originated in the Midwest, it is a term to describe when a guy goes to finger a girl, but because he is totally trashed, he winds up getting her in the butthole.  Some believe it stands for "Anal Jackhammer"

Get the Ajmug. AJ is the type of person you will only come across once in your life time. He is one of the sweetest and most caring people you will ever meet. He has a great eye for all things music and a unique personality. He is kind, understanding, thoughtful and very selfless. He always keeps your best interest at heart and will do anything he can to keep you happy. There is no one like an AJ.
