pissing in the bin

An act of exemplary absent-mindedness.

The expression is derived from the occasion when one urinates into a receptacle in the bathroom other than the toilet due to not paying attention to one's actions or surroundings.

How did John miss that exit? He must have been pissing in the bin.
