In porn, a black hole is when the guy is doing the girl missionary or doggy style, and the camera is behind the guy showing his anus. Staring into the black hole will steal your soul.
I was watching Do It Doggy Style, when they kept showing the guy's black hole. I didn't want to lose my soul, so I turned it off.

A ridiculously hairy asshole, so dark it gives the appearance of a black hole.
Alex just showed me his black hole.

a theory of an object in space, which is believed to consume anything, that enters into it.
Kyle thinks blackholes are Fact, but he's an idiot so a blackhole must have consumed his brain.

The act of "docking" ones anus with another's anus. Similar to the docking of uncircumcised male weeners only, this time its anus edition. Like two intergalactic black-holes ripping asunder the very fabric of space and time; light could never escape these converging holes!
Hey, get that crusty anus over here and black-hole me!

I met this rockin boi at the mall today and he totally asked me to black hole him tonight. Better clean out the old wrinkled raisin!

"Sir, the ship is passing between two black-holes now"
The captain grabs a glass of whiskey raising the plastic edge to his lips,
"God help us all..."

A black hole, according to the general theory of relativity, is a region of space from which nothing, including light, can escape. It is the result of the deformation of spacetime caused by a very compact mass. Around a black hole there is an undetectable surface which marks the point of no return, called an event horizon. It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect black body in thermodynamics. Under the theory of quantum mechanics, black holes possess a temperature and emit Hawking radiation, but for black holes of stellar mass or larger this temperature is much lower than that of the cosmic background radiation.

Despite its invisible interior, a black hole can be observed through its interaction with other matter. A black hole can be inferred by tracking the movement of a group of stars that orbit a region in space. Alternatively, when gas falls into a stellar black hole from a companion star, the gas spirals inward, heating to very high temperatures and emitting large amounts of radiation that can be detected from earthbound and Earth-orbiting telescopes.
"Astronomers have identified numerous stellar black hole candidates, and have also found evidence of supermassive black holes at the center of galaxies. After observing the motion of nearby stars for 16 years, in 2008 astronomers found compelling evidence that a supermassive black hole of more than 4 million solar masses is located near the Sagittarius A* region in the center of the Milky Way galaxy."
