A wet willy but in the Butt

Penetration, prison style

the act of putting your finger in your ear and placing in ones mouth

this is where you stick your finger in your ear and get a shit ton of ear wax on your finger, then shove your finger in someones mouth.

in the same family as a "wet willie", but instead of licking one's finger and penetrating another's ear, one would directly penetrate their tounge into another's ear in order to directly transfer the saliva.

When someone is asleep, you wake that person up by licking the person directly in his/her's ear

The act of giving a regular wet willy but instead of saliva, you stick your finger up your nose and then in the victim's ear.
