look up any word, like sex:

1 definition by Trii

The act of placing something, usually a finger, in your butt crack and then wiping the something on someone else. The goal of the butt-winkle is to transfer your butt stench to someone else.
I was joking around with my girlfriend last night after the gym and gave her a butt-winkle. Now she won't sleep with me because all she can smell is my ass.
