N't is an explosive building built by Warui to store all his "Nega'ive Technology". Currently, it's housing Wa-Machines and a flash drive with all versions of Windows past 98, but N't is also the opposite of everything. At times, "n't" stands for "n' The previous verb has been made NEGATIVE!". Not many people know about that last definition, and stick it on places it shouldn't be, like on nouns, thinking it's the fraternal brother of Un when in reality n't is just a weird way of spelling trinitrotoluene, which you might know better as TNT.
In the series Breaking Bad, N't makes an appearance in the famous Jessie Pinkman catchphrase "He can't keep getting away with it!"
History[]
N't was first discovered some time after William Shakespeare conquered English in 1610. He hated how English wasn't having contractions, because during the Napoleonic wars he impregnated English so that it could give birth to epic french loanwords like email. As a byproduct of this, apostrophes was introduced into English. The first word added in this update was didn'tst, with other auxiliary verbs following suit. He also started adding it to words with V like ne'er and 'al'e. Also, Not died during this time, which gave N't more power.
In the 22nd century, the UnAnything Team and the Anythingn't Team got into a super heated debate whether or not Un- or -n't should come before/after the opposite versions of words. Eventually, the courts agreed that Un was the UnWrong one, because you can add it to any word to make it wrong. The courts sent N't to WaJail for 30 years, alongside the entire Anythingn't Team. Not from earlier was revived during this time, thus N't was pretty much pointless after this, but there are still some diehard N't left who can't get with the times. Or those who aren't on Mac.
