A male takes a shit. As males are wont to do, he stands up and looks down upon the mighty work his anus has wrought. After the proper time has passed and propriety has been suitably satisfied, the male may then aim his piss to break the shit clumps into progressively smaller turds*, evocative of the classic Atari arcade game Asteroids. This effect is especially poignant if the feces are of the "Floater" variety.

*It is said that the man who manages this feat most perfectly will subsequently gain entrance to the Outer Ring of the Seventh Circle of Hell. He may then, if he were so inclined, feed his frothy shit smoothie directly to Hitler, who resides therein.
Lucifer 4:19 : Verily, passageway shalt be granted to the mortal who, with his properly directed discharge, doth break up his droppings sufficiently so that none greater than might clog a small thimble remain. Yea, this deed shalt hereto forthwith be referred to as "Achieving an Asteroids".

Any rock floating about in outer space. There is a whole bunch of suck rocks floating about in outer space between the earth and mars, and this is known as the asteroid belt. When a stray asteroid gets heavily influenced by a planet's gravitation field, when it strays to close to the said planet, and eventually ends up crashing into that planet, the asteroid becomes a meteorite. If it does not end up crashing in, but grazes the atmosphere, or burns up in the aire itself, it is known as a meteor.
One of the largest asteroids is named after the gaulish God of the sky, Tautatis.
