freudian finger 

When you give someone the finger so subtly, even you don't know you're giving it.

I didn't realize I was freudian fingering him, but I scratched my nose with my middle finger, unbeknownst to all.

Freudian Fingers 

When you type a word or words unintentionally, but the mistake still has (unintended) meaning or appropriateness to the situation.

Actual Freudian Fingers:
I meant to type, "I want to smack him so bad!"
I actually typed, "I want to spank him so bad!"
Or
"Dammit! Boob really messed up this time!" when you meant to type "Bob."
