Crud Eater

Someone who eats up all your crud. Typically, the crud that comes out of girls mouths.

A person who believes all the crud that someone says. AKA a complete duster of a person who blazes. An absolute mockery.

Also, a crud eater will often be told to cut the crud.

"Sup you crud eaters?"
"Cut the crud"
"You're being a crud eater."
