Words or phrases people use too much
I've noticed a lot of people from young teens to late 20's literally say "literally" every couple of sentences. And, almost always, they don't really mean literally. I don't think they even know what it means.
For example, recently I walked around a corner and almost bumped into someone, startling them. The guy says, "Woah! I literally just shit a brick." As it happens, no masonry was expelled from his butt, and as it turns out, he didn't soil his pants in any fashion at all.
I also think the British say "brilliant" way too often.
Any other phrases that bug people?
