Person B: "Dude, I know what you mean. My beer bottle just broke and I don't know why. I didn't think being a drunk could be so complex."

Person A: "What the fuck are you talking about?"

Person B: "Why are beer bottles so complex, and why do they lead to the birth of unwanted children?"

Person A: "Why must you go off on such a tangentation?"

a tangentation is an explanation of a situation(s) or event(s)or both but not limited to only that.it can also be about your trip to the store and what happened in your venture..perhaps you stepped on a cats tail which caused the clerk at the store to go ape on you as she was an animal activist,or the cat bit your ankle which in turn caused you to fall on a board with a nail stuck in it and it peirced your ear,which was great,because you saved so much time and money,relieved by this..you donated your proceeds to the animal activist fund in your area
ok, so perhaps that tangentation was a little far out,but really,tangentations exist everywhere and no-one has had the time to come up with a solid example of how to express what this could lead to.this word will spread like wildfire if you just start rambling on into other topics to only arrive at the original topic in which you started with!

To "go off on one".... To rant aimlessly, or even aimfully but never stick to one topic.

When shiney new words, information and concepts distract you in conversations or in writing.

When you're interested in everything all at once.

Common to, but not specific to ADD or ADHD; but also personality.
Murph: "heeeey girl.... Do you remember that perfume we used to wear in high school? Gosh what was it called?!"

TangentGirl: "ooooh yeah! It was also called wild lagoon by Coty, the base note was vetiver essential oil, but did you know these other 20 perfumes we like have that same base note! Oh here's a recipe for making your own perfume, oh did you know that there's a word for having a fetish about smells, ooooh or that the guy who made that used to work for Chanel, oooh remember when we used to buy that other one too, oh or fake version of CK1, and then remember at prom the first dance song was Words by Boyzone... And I had curly hair.... Gosh.... don't you miss walks along the coast at night coming home from that nightclub without our shoes on?"

Murph: "...............”

TangentGirl: "Murph.....?”

Murph: "Um.... So it's called Wild Lagoon then?"

TangentGirl: "oh god no... That was just in Europe, it's called Monsoon by Coty"

Murph: "Mmmm-K.... Imma gunna go eat dinner now... Breakfast has gone cold"

A tangent is a "computer". Except, not really. It will contently break, almost never work, and crash with the blue screen of death often. All at the University of Dayton wonder why they are required to use such terrible "things". A tangent is equivalent to a 1995 Gateway computer. It can not run windows Vista, yet it tries anyway. Often problems are windows explorer not working, sound deciding to stay on or off for an undetermined amount of time, dvd drives to not work, shut down not to be an option, screens to randomly shut off, hard drives to out of nowhere not know who you are, keys to break off, buttons not to work and such things.

It is also defined as a paper weight or a large expensive portable DVD player.
