The term that physicists use for preventing a man from having sex with a woman (i.e. "cockblocking"). Single slit interference refers to cockblocking just one guy, whereas double slit interference refers to cockblocking two different guys.
"I observed some single slit interference last night in the lab"
"With a laser?"
"Nah man, roger was trying to wheel his lab partner but this other dude spilled some chemicals on her and she had to go to the emergency room."
"I hate when that happens"

Get the slit interferencemug. 
An odd and peculiar sexual fetish where the woman is on her back and rolls on to her shoulders presenting her pussy to the sky. The man, or woman then steps between her legs into a scissoring position and then proceeds to fire a hot log right into her vagina. This obviously only works if the turd is relatively hard and/or the pussy is extremely loose.

Get the moldy slitmug. No matter how much extra sharp ginger brandy he's had to drink, my friend Tommy always finds the weiner slit.
