leaky aircon
While your girlfriend is sleeping you shoot a rope on her cheek. When she wakes up and says "what the fuck?" you point up to the air conditioner and say "I think we have a leaky aircon".
Example:
My girlfriend wouldn't blow me earlier so I waited till she was sleeping and gave her the leaky aircon.
