Every once in a while, I hit upon a word that tickles my echolalia and thus find myself possessing a strong urge to repeat it or use it at every opportunity. Usually the word is "woobies" and to a degree still is...however, I now have a new one:

Asshat!

To be honest, I don't entirely know WTF an "asshat" is, just that it sounds highly amusing. I saw it on one of the LiveJournals on my LJ Friends list, promptly began snickering, and within ten minutes, was not only chanting "asshat" but referring to virtually every even-slightly-annoying creature or person as an "asshat."

I'll bet my parents are happy I didn't find this one when I was young enough to be their problem. *snicker*
