1 definition by Dr. Plague

A hole in which masting/mastering occurs, also known as master hole...note that masting in this definition is the act of ejaculating or engaging in some kind of sexual act. A clever but somewhat obvious term to be used in public to deter strangers from eavesdropping on a sexual/private conversation.
