An expression used for telling someone to shut up when they've been talking for way too long about something nobody cares about, especially when the subject matter is an obscure/poor quality piece of media or pseudocelebrity.

The quote itself originates from the youtube channel "Funhaus", when Bruce Greene interrupts the others as they're having a conversation about the movie "Lawnmower Man".

Bruce: "Stop talking about. Lawnmower. Man."

Guy 2: Hey man, you better stop talking about lawnmower man, you're scaring the hoes away.
