look up any word, like cunt:
 
1.
1a When the uppermost of the two sexual partners engaging in the classic 69 position, defecates on to the other participants face. The true 'mud goggle' effect isn't reached until the stool droops over covering both eyes.
2a when your friend makes a potential mate out to be less attractive than they actually are, because of foul mood -they are said to be wearing "mud goggles"
a. Steve gave Martha some awful mud goggles last night, he probably wont ever see her again
b. Jessica sure was attractive, but mark said she was a real shovel face poor guys wearing the mud goggles tonight.
