Similar to the butt plug, but for the gash. Often used to promote a sensual experience in the poon but can also be used in the axe wound, slit or lobster pot. Also used to prevent leakage of the dripping delta or wishing well. Frequently found in the unmentionables section of your local supermarket.
Thanks to my gash clogger, I no longer have embarrasing leaks coming from my panties.
