disco bag
A condition where the scrotum has been covered in glitter and drawn through the fly for the purpose of enhancing a party, office, office-party, cubical gathering, performance review, Christening, or Ba(r) Mitzva, much like a disco ball at the roller rink in the '70s and '80s.
We thought for sure Tranny Pat was post-op, but (s)he whipped out a disco bag and lit up the dance floor.
