There’s a decent comedy routine by Seinfeld where he talks about male thinking. In his view, the most masculine idea of all-time was flying all the way to the moon, than driving around it for a short distance in a little car. That’s pretty hard to beat. Can you come up with a better example of male thinking? If not, a close contender?
Anything involving the phrase “Ramming speed!”
Monster trucks. Everything about them. They’re TRUCKS…and they’re REALLY BIG…and you can even RUN OVER OTHER CARS!
Insane Chainsaw Hedge Trimming
How about jumping from an airplane into an erupting volcano while riding a shark with 250 lbs of dynamite strapped to your chest?
Writing your name in the snow?
That’s the winner!
Went to a monster truck show a few years ago. 2 of the drivers were women, they were just as good as the guys.
My guess would be getting hit in the nuts on purpose.
Sorry I can’t find the cite, it was something I browsed once for ten minutes nearly forty years ago. But once upon a time I came across an example of the SF porn genre that was written in the 1950s or 1960s. The title was something like “Conquest of the Lesbian Planet” (except no search matches by that name). The plot was that Our Hero has been biologically engineered to be superhumanly potent and is sent to neutralize the threat from a planet of amazons. Skipping to the end he becomes the immortal God-Emperor of the planet surrounded by his adoring harem.
If there’s anything more piggishly masculine than this I’ve never come across it.
Might makes right
“The Duck Joke” (skip ahead to 5:45 for the punchline).
The sword is mightier than the pen.
How about Truck Nutz? I’m pretty sure those were not invented by a woman.
That answer has a lot of heart. But a football in the groin is a football in the groin.
Depending on whether you (= me really) interpret “SF” as standing for San Francisco or for Science Fiction really changes what you expect the rest of that paragraph to be about. 
But yeah, you win the thread so far, at least in the fiction / entertainment division.
Or, to bring it down a notch from Sci-Fi (or San Fran) porn fiction into the real world, there’s nothing so “masculine” as being the super studly stud who knocks up every hot chick he can get his hands on relevant body part(s) in. Extra points for leaving them pregnant and abandoned to their and their babies’ fates.
OTOH, getting laid and becoming a responsible father to your female partner-in-getting-laid and your children, this either gets you bonus points or you lose points depending on the attitude of any observer.
I’ll raise you James Bond. Handsome, dynamic, witty, sophisticated, gets laid all the time and has a license to kill. Women want to be with him, men want to BE him.
