upspeak
Affliction affecting my in today's society not just teenagers where a person makes a question out of a sentence that isn't a question (or more simply speaks "up" at the end of a sentence). Huge part of most American and European accents. In some languages such as French or
Spainish it is actually required as part of the accent but has seeped into the English language perverting the grammar of sentences, annoying the hell out of some and showing the widespread influence of US TV like Friends and
Sex and the City on accents (particularly in the UK and Ireland)
