The presentation of the scrotal sack, within a pair of knickers. Arranged to represent a oversized
set of vagina lips (labia)
This is then most commonly photographed and sent via text message to as many
people as possible.
The best examples either convey a very extreme
mess of a vagina, or
try to look as close to a vagina as possible. Putting doubt into the viewers mind to whether they are looking at, Balls Flapping around a pair of knickers, or actually just a vile vagina.
