"The Fear" is a feeling of intense paranoia, nausea and insecurity that you sometimes get after heavy drinking.
Anyone can get The Fear. Some people claim they don't get it, but they're either hideously secure or well-behaved. Other people claim that they only started getting The Fear after being told of its existence; a more likely explanation would seem to be that they simply didn't have a name for it before…
There is no known cure for The Fear.
What the hell happened last night? I think I did something really bad, but can't remember exactly what... I've got the Fear!
