The longest word in the english language. Is very hard to pronounce and is usually used by high shoolers to look smart but when is is said around people who dont know the word, it tends to reeeeeeeeeally confuse alot them and then they stare at you like your some kind of freak and then (after a painfully long awkward silecne) they usually say... "WTF MAN!!!" or "Umm... ok..... i'm... going... to... stand... over... here... now"
Person 1: hey guess wat
Person 2: Wat?
Person 1: Antidisestablishmentarianism!!!
Person 2: ...
