The act/art of going into a public place dressed as Batman, and acting as if nothing you were doing was unusual.
"Hey you should come with us this week end! We're heading down to Taco Bell to go Batmaning!"
Similar to the Superman, a man places his ejaculate around the waist of a female and then places toilet paper on said ejaculate. The result is a belt of toilet paper that is similar to Batman's utility belt.
Last night, I straight up batmaned that hoe.
A "superhero" with no powers - just a shitload of cash, bunch of gadgets, and a super-loyal butler!
Superman - "Need any help?"
Batman - "No thanks!" (kicks villain in the crotch)

When you grab each side of your nut sack and stretch it as far each way as you can. Then, you get some jackass to look at it. You then scream batman and meatgazer to attract attention. Finally, you are allowed to kick him in the ass 3 times calling him a fag each time.
I grabbed my sack and made my adhad ass brother look at my batman. All steps followed.
