What is Crusty Muzzle?
1.
This is when you are having sex and the woman that is so loud, she wakes up your roommates causing you to take the crusty old jerk-off-rag (SOCK) from under your bed and cram it in her mouth.
Kristen was yelling so loud at the apartment during sex that i had to give her the crusty muzzle so she didn't wake you up.
