The sexual act of having your partner laying on the ground, butt cheeks wide open, and you jump from the top of your bed and land with your penis in their ass.
Friend 1: Did you batmaning that girl last night?
Friend 2. Yea bro, her butt still hurts.
Standing on top of a building and looking down at a city for no explicable reason often to monologue or just pose.
Also known as, Dramatic High Perching, or spidermaning (although this typically involves a squat).
A: You see that new action movie?
B: Oh yeah, the main dude spends half the movie batmaning on buildings all around the city.
A: lol, looks cool though,
This is an advanced sexual act, performed when one is feeling in the mood to surprise ones lady. You start this delight by turning off all lights in the room. Get your lady to lay on her side and ask her to look at the ceiling. Now, grab your erect meat seeking pissile and shine a torch from underneath to display the sillouette on the ceiling, while screaming "TO THE BATCAVE" and with one swift, vigorous thrust, insert ones member into her anus. Lube is optional, but dry docking is not recommended unless you do not value your teeth/balls/relationship.
I gave Tonya a real good batcaving last night. Luckily, she enjoyed it so didn't evenknock my teeth out afterward.
Criminal 1: Shit...it's the batsignal!
Criminal 2: No, it's a bat with a sombrero on it.
Criminal 3: Don't you guys know? Batmang and Brobin are on their way. Let's scram.
