Eyemuffs 

The act a young child or sensitive person does when something potentially crude or inappropriate is about to be shown. The specific action is simply covering the eyes to shield the lewdness.

Dude: Yo, check out these monkey brains between my legs?

Dude's unsuspecting girlfriend: What?

Dude's Friend: You might want to Eyemuff it.

Dude's Unsuspecting GF: Eyemuffs?

Ewww gross... Though they do really look like a monkey's brain.

Similar to an earmuff, but covering the eyes. Used to protect young children from viewing unsuitable material.

Person 1: Check out this pic of boobies.
Person 2: Eyemuff your five year-old son first.
