Direct and immediate response to any sort of sleep rub or other tricksy sexual behavior introduced after your girlfriend decides it is time for sleep. To ensure "it's not going to happen" doesn't happen to you, enter bedroom in your hotpants as your girlfriend requested.
Male: Uhh babe... wake up! Right Here... Sleep Rubs!!! Off!! Come on...

Female: (lying on stomach with arms above head, mumbling and obvious that tomorrow will produce no recollection of said event) Uhh, It's not going to happen...

Something you tell a guy when it's just NOT GONNA HAPPEN. Must be said in a high volume or tone so that all parties within the unit know he's not getting any.
Girl: What are you doing over there... are you getting a CONDOM???
Boy: Ahhhh noooo, just grabbing my wallet... (as he reaches into roommate's nightstand drawer)
Girl: Not. Going. To happen.
