Stop talking about lawnmower man 

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."
(At a party)
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.

Man stopper 

Quite simply a man stopper is a tampon. Encountering a tampon inside of a woman while attempting to have sex with her will stop a man in his tracks.
We were making out, I got her top off, she seemed good to go but when I tried to finger bang her, well God dammit I ran headlong into a man stopper! That was the end of that night.

Manstopper 

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.
Dirty Harry didn't mess around. His .44 Magnum was an absolute manstopper. Do you feel lucky punk?

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
