Roflcopterd 

A word used to describe something that was meant to be "roflcopter"-tastic, but alas was not so funny. Thus the moment/joke OR the person who created the moment/joke is referred to as a roflcopterd.

"and then, ha, and then the salesman was just like 'no!'"
-did we really just listen to your story for that?
--What. a. roflcopterd.
