Tinklepuff

Tînk'-el-puf (noun) The act of a man and woman sharing a simultaneous evacuation of bladders into a common toilet. Specifically, the woman sits on the toilet and urinates in the traditional fashion, and the man stands facing her while urinating between her legs. The purpose of this arrangement is to encourage efficiently of time and facility use. The name originates from the concatenation of the pet names of the inventors. Traditionally, the invitation to perform a tinklepuff is either accepted or rejected immediately and without deep consideration.
