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.

Noun: A completely and utterly worthless computer company that sells blocks a shit, aka laptops, to college students. The company attempts to conceal their horrible product by including "exclusive" university features. What they don't tell you is that you can by a laptop for over \$1,000 cheaper that is better performance-wise, and those exclusive programs are free from the university website.

Can also be used to reference a worthless piece of crap, or a dick move.
Student 1: "Wow, this is the fifth time in a month I've taken my Tangent computer in. What a piece of shit."
Student 2: "You should fake an accident to your computer and get the warranty money. Buy something better."

Kid 1: "My car broke down again."
Kid 2: "What a fucking Tangent."

Kid 1: "Dude, Tangent move..."
