Invisable Girl 

After sex with your partner you go about your daily routine in their house acting like you can not see or hear them.

Dude, I got to do the Invisable girl to this woman last night.
Did you tell her that you were doing it?
Of course not.

Invisible Girlfriend 

When one sits on his hand until it's numb. Then proceeding to jerk off and imagining your "girlfriend" is jacking you off.

I'm so lonely that I had an affair with my invisible girlfriend last night.
