Devil's Triangle 

A drinking game form the early 1980s where you place three beer filled red solo cups equidistantly on a table. Then attempt to bounce a quarter into the cup. If the attempt is successful, the player gets to give the person of their choice a drink. If you make 3 attempts in a row, you get to make a rule. Common rules include things like:

No names - Can't say any other players' name.

No swearing

No pointing

Must perform a particular action or say a phrase before bouncing the quarter.

Christine was not very good at Devil's Triangle and it has ruined her memory, so that she falsely accuses fine upstanding young men of dastardly deeds.
