The Bloop was a sound that was heard by the scientists in NOAA (Well, a few heard it), which was pointed out to be either the sound of Cthulhu's wailing, or a freaking mermaid. And that's very creepy. These mermaids seem to be creepy. Very. OK, off-topic. If you want to know more, go to Wikipedia.
Crap, "the bloop" was scary as hell!

Did that mermaid make "the bloop" again?

The type of (clean) bowel movement where the excrement are tiny and ball-shaped, resulting in a “bloop-bloop” sound when they break the surface of toilet water. When more of these droppings are released in a continuous and repetitive fashion, the longer the bloop-bloop will be. Some bloop-bloops are known to cause such splashes that will spray toilet water back up the rectum of the depositor. This is known as toilet backdraft.
