What is Flash The Gash?
1.
Phrase commonly used in "jest". Taken from popular game show phrase "Flash The Cash". Means, basically to get your vagina out for display purposes and amusement. Not to be taken seriously, however some females may actually flash it on demand when given the command. So beware if you are not fully expecting to experience the sight of a females gaping axe wound/vertical bacon baguette.
"Oh come on love, just FLASH THE GASH!!!"
"There's no-one lookin', just FLASH THE GASH!!!"
