The act of inserting the index and middle fingers into the vaginal opening, and the middle and pinky fingers into the anus, or vice-versa. This is similar to the "shocker," but adds an operative finger. It is also called the "spock."

The Milwaukee Monster was adapted from the famous "Live Long and Prosper" hand signal from the Star Trek series. Legend has it that the origin of the name was when a friend was explaining the move, and the listenener misheard "Live Long and Prosper" as "Milwaukee Monster." The speaker agreed that this was a better name, and thus the current name.
