A sexual position/event taking place during a threesome (one guy and two girls). It is when a man is standing and receiving head from a girl on her knees but also at the same time a girl comes from behind and tosses his salad.
The creator was once withdrawing money from an ATM late at night when he was held up at gunpoint. He was happy to pull out cash from the machine but was soon terrorized by the mugger behind him. Therefore he thought 'midnight robber' was an appropriate name for the sexual event described as above.
Yo Sage, how was that threesome you had last night with those two nurses?
Dude, it was crazy hot until they decided to run the midnight robber on me!
