This is a special case of a Big Kahuna, itself a large turd. When any portion of the turd sticks above the waterline, you have created a Brown Iceberg. Much like it's icy namesake, the vast majority of the Brown Iceberg lies below the surface. When turds have achieved this dangerous size, it will often not flush down the toilet, resulting in a Pooplug.
A chart that sorts facts/theories from a piece of media by obscurity, usually the most commonly known subjects near the "tip of the iceberg", and the lesser known subjects being near "the abyss". The images used to separate the categories often get more ominous and disturbing the deeper the chart gets.
The receiver floats in a briskly cool body of water. The nipples must be fully erect prior to this maneuver. Meanwhile, the penetrator begins to climb upon any platform at least three meters above the surface level of the water. A perfectly timed dismount from the elevated surface will result in a deep, powerful insertion.
Only the part of something that can be easily observed, but not the rest of it, which is hidden. (Referring to the fact that themajority of an iceberg is below the surface of the water.)
A photograph that has been posted on any social networking site by a large person in which they appear to be of normal size, usually taken from an elevated angle or just a head shot, like an iceberg...only a small percentage of it is seen from above the water.
