To hide one (or more) bottles of the horrible english beer "Old Speckled Hen" in a friend's residence. When more than one bottle is being hidden it is customary to place one bottle in an obvious location, thus alerting the "victim" that they have been speckled and another bottle has been hidden more cleverly.
Hey girl if you really want me to go through the labor of making you a mojito first you gotta show me ID, and then you've gotta make all these dudes bust in a glass and finish the entire spermino.
