2. shit willy (n.) - Slang for a the sexual acts of having anal sex and then ear sex in close succession.

3. shit willy/shit willied (v.) - The act of giving someone a shit willy, whether it be from either definition.
1. Bryce gave me a noogie yesterday, so I waited until he was looking the other way, I stuck my finger up my butt and gave his ear a mean shit willy.

2. Me and her did the shit willy last night, so boy am I really sore and she is having trouble hearing.

3. I shit willied the hell out of her and gave her one mean ear infection. You know what they say, once you go black you go deaf.
