fourth dimension 

The fourth dimension is time, as defined by Einstein in regards to the Theories of Relativity. The Spatial dimensions are those of height, length, and depth. The fourth dimension can be related to a hypercube, much as the first dimension is related to a line, the second two lines connected at perpendicual angles to one another, and the third dimension being a cube. The fourth dimension is(sometimes) associated with the space-time continuum.

It is truly inane to travel to a universe that is based only upon the fourth dimension, as that woould include only time, and no being could truly exist.

Thot Theory of the Fourth Dimension 

Theory that states and defines the question of why men pop random boners.

The theory states that when you encounter an awkward/random boner in any given time or place, it is solely because in the fourth dimension, a thot is riding you, but in result of the natural phenomenon being in another dimension, you cannot witness this firsthand with your own eyes. The only physical act you feel is having a random boner.

There have been numerous cases of people who believe they can perceive the fourth dimension, that have "witnessed a thot ride them" in a location where no one could gain access to in the real world, such as a house or bedroom.

Other encounters include people stating that these mythical thots riding them "so hard they almost pulled me into another realm of concience and time".

"Man, why do I always pop a random boner in class?"
"Woah man, your out-of-dimension-thot is into that kinky school girl stuff"
"Out-of-dimension-thot?"
"Yeah man, have you ever heard of The Thot Theory of the Fourth Dimension?"

Fourth Dimensional Bong Hit 

A Fourth Dimensional Bong Hit is just like every other bong hit, with the difference being as follows:- <A> you haven't slept in 4 days, <B> someone has packed it with hash crumbs or oil without your knowledge, <C> you only smoke spliffs and you've been peer pressured into having a hit from a bong, <D> You've only just been able to get some green, but have had to go without for a long time (if you're a daily smoker).
Generally it is marked by a vivid blue exhale that lasts several breaths, and many coughs and splutters. Probably the cause of the term "Young Lung".

"...so one time I had this Fourth Dimensional Bong Hit and coughed so hard that my room mates found me face down in a pool of my own vommit... Luckily I didn't spill the bong water though..."
