chair party 

The act of celebrating a great moment while sitting down and playing a game or working. Dancing and giving high fives while remaining seated.

When I finally tamed the dragon with my GM Tamer, I threw a total chair party!

Chain Party

A non-stop party often lasting days at a time.

It can change location as it runs out of supply (booze, smokes, pingers, etc.)

Jack: "Oi, let's have an invite all and chain party this weekend!"
Jill: "Sounds great. We'll go to your house first then mine after we run out of booze!"

part-time chair 

A chair that is not in use at the particular time it is being spoken about. Examples include folding chairs, reclining chairs, or chairs that one would not necesarily choose to sit in for comfortability.

Were having some family over tonight, can you bring the part-time chairs up from the basement?
