Girl 1: "God, I gave myself three orgasms last night, but this morning I have a horrible case of jackhammer clit!"
Girl 2: "I know, right? It's that damn Hitachi, it just works too well!"

Similar to Midnight Hovering, Midnight Jackhammering is the act of using a vibrator in the middle of the night. Not just any vibrator though. Oh no, this vibrator is so powerful it could be used to remove the limescale from the walls of caves...it is usually referred to by the person in the next street - anyone living with three buildings of someone doing this would have to wear ear defenders and have some serious underpinning done to their building.
Jeez....I got no sleep last night - girl four doors up was doing some Midnight Jackhammering....put my hard hat on - thought my walls were gonna cave in..
