I came across this word for the first time a month or so ago and thought it might be worth sharing: Eponysterical.
“Posts and comments which are funny in light of the poster’s user name”
http://www.urbandictionary.com/define.php?term=eponysterical
The word’s origin seems to be here:
“I think the adjective should be “eponysterical.””
So, have you used this word in conversation today? If not, why not!
