Witch Finger 

The penis of a really hot girl that comes as the worst surprise at the worst of times.

Or as seen in Clerks II, a girl with a very large clit.

"Yo man, that girl was so hot, but then I went to go down on her and she had a witch finger."

"Randal Graves: Emma, are you like this 'cause you have an unnaturally large clit?

Emma: You just *had* to tell him, didn't ya?

Dante Hicks: It kinda came out one day!

Randal Graves: He says it's so big it's almost like a little cock, which says all kinds of weird things about him that I don't even wanna think about."
