unthusiasm

Lack of enthusiasm.
Either sarcastic enthusiasm, or from boredom.

Unthusiasm

The act of feigning enthusiasm.

Usually sarcastic, but can sometimes be a means of gratifying a dull anecdote.

"I had to use my unthusiasm to get rid of that guy."

"Hey man, no need to use unthusiasm on me."
