Perhaps, as the party gets more riotous, you'd prefer games with some physical action. One of these is Clench-Racing, whose inventor Nick Lowe recommends it as a great way to get thrown out of bookshops. Up to six can play. The rules are simple: each player takes a different volume of Stephen Donaldson's blockbuster Chronicles of Thomas Covenant, opens it at random, and leafs feverishly through the text. You win by being first to find the word "clench" (or "clenched", "clenching", etc). It's a fast, furious sport, and a round rarely lasts a full minute.
The original point of Clench-Racing was to highlight Donaldson's peculiar fondness for this gritty word. If players get too good at locating "clench", Lowe slyly suggests switching to "other favourite Donaldson words like wince, flinch, gag, rasp, exigency, mendacity, articulate, macerate, mien, limn, vertigo, cynosure ..."
What do you think, sirs?
I have never heard of that particular game before, but SRD does seem to have a select few unusual words that appear more frequently than others in TCTC. I don't remember seeing many occurences of 'macerate', though
