When somone wets their finger like a regular wet willy but dips it in some busted up weed and sticks it in someones ear while screaming "WEED WILLY!", leading to little bits of weed inside their ear and them getting mad about it more so than a regular wet willy.
Weed Willy!!! Fuck I hate when you weed willy my ear.
