Get the Bill Cosby mug.
A cocktail made so strong that it could lead to future rape allegations against the server. The original drink can be made from any base ingredient such as coffee or juice but will usually be laced with barbiturates, Quaaludes or other knock-out tonics from back in the day. Also see Mickey, rohypnol and Date Rape.
