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".
Lawrence: "The Lawnmower Man director, you could tell he was really building up to it cause he teased-"
Bruce: "Stop talking about. Lawnmower. Man."

Guy 1: If you're gonna watch Waterworld, you'd better watch the Ulysses Cut or else you'll be missing out on a lot of scenes that help explain more about the world. It also helps you get a deeper understanding of the Smokers' religious beliefs and their ability to refine-
Guy 2: Hey man, you better stop talking about lawnmower man, you're scaring the hoes away.

Can refer to any large caliber gun or bullet that will immediately "stop" a person with one hit. You might live from receiving a limb shot. But there is little to no chance of surviving a hit to the head or body. .50 AE, .45 ACP and .357 Magnum are popular calibers know as manstoppers. The larger the better.
Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".
