A dribble glass is a drinking glass that has holes hidden in its etched design. [1]
The purpose of a dribble glass is for pranks. When a person tilts the glass to take a drink from this glass, they will end up spilling the liquid on their clothing as the drink trickles through the holes. [2]
In ancient Greece, sculptors created so-called "dirty trick vases" that featured a small rectangular hole in the foot of the vase. [3]
