It's kinda specialized, because I love early literature and music, but one peeve of mine is the the misuse of "willy-nilly." People use it to mean hurriedly or carelessly, but it actually means whether he wanted to or not.   Will-he or Not-will-he.

The hill was steeper than he thought, and he pelted down it willy-nilly.

Often when people use willy-nilly, they should use helter-skelter, meaning in hurried disarray.

Steve, no matter how many other people goof it up, up I will not accept the substitution of literally for virtually.
