When a male goes to a social gathering (such as a bar or club) and tries to chat up every female at said gathering.
A male in machine mode who gets knocked back by a female, will quickly forget about the female and move on to another female, often the nearest female to the first female and probably the first female's friend.
Friend 1 @ a club: "Alright mate, where you been for the last hour?"
Friend 2 @ the club: "No time to chat, I'm in machine mode tonight, I've already been knocked back by half the girls here... time to move on to the fat chicks. Later."
