Penthusiast 

A word to describe those people that LOVE stationery. It is a portmanteau of 'pen' and 'enthusiast'. It is a pretty self-explanatory term: an enthusiast is person who is highly interested in a particular activity or subject and in the case of a penthusiast the subject is pens. And all their 'cousins'. (i.e. highlighters, erasers, hole-punchers, etc.)
Such people would move into an Officeworks store in the blink of an eye if given the chance.

Abby: So what are you getting Ursula for her birthday?
Mavis: I got Ursula this massive box of Crayola Crayons and some Derwent charcoal pencils.
Abby: ... Will she like those?
Mavis: Oh yeah! She's a total penthusiast. She could live in Officeworks! If you want her to fall in love with you forget sending chocolates and roses, send her post-its and blu-tac.

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."

unthusiasm 

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

1) Woop. Wa-hey. Yeah. This is fun.
2) Nice going with the unthusiasm there.
