[Fictionary] Candidate word for round the next!

[Jim Moskowitz]

Let me first say that I'm surprised to be running this round, since 
it marks twice in four months -- when I think I had won twice in the 
entire previous decade.  I figured my def for flifflis would be seen 
as too close to effluvia... but evidently not!

My candidate word for the next round is:  pyknic

If you know its definition already, please email me in the next 54 
hours; otherwise, I'll officially announce on (my) Thursday night 
that it's a go for this round.
