Formerly known as "the Dirty Sanchez", a Screech is when a man wipes his penis across a woman's upper lip after engaging in anal sex with her thus leaving a mark that resembles a Mexican mustache.

The term "Dirty Sanchez" was overtaken by "Screech" as the most popular term for the sex act when Dustin Diamond who played Screech in the 90s TV show 'Saved by the Bell' performed said act on some poor groupie.
