2 Twi'leks, 1 cup

2 Twi'leks, 1 cup was a well-known short holo-film that circulated amongst the HoloNet for many years during the Galactic Civil War. A pornographic piece, it centered around two female Twi'leks, both green-skinned, having sex. The twist was, however, that one of the women would eat the other woman's excrement.

Thankfully, the meme eventually played itself out.
