When a man, during sexual intercourse, uses their thumb to plug any open orifice on their partners body.
"So I heard you took that girl home last night. What happened?"
"Well the girl I brought home saw my m92 Krinkov kit and started leaking profusely out of her vagina. So I hit her with a Kentucky plug."
