Prairie-masker

[Mark Zuckerberg]

A Prairie-Masker is when a girl gives a blowjob while she has an [Alka-seltzer] tablet and some water in her mouth.
The definition was coined abord U.S Naval [submarines], named after the Prairie-Masker anti-sonar detection device employed by submarines. The Prairie-Masker anti-sonar system works, in a nutshell, by creating a barrier of bubbles around the ship thus reducing noise and detection by hostile [sonar] devices.
