1) Board game played by members of the educated upper-classes. Each player is distributed a number of abstruse grammatical items including hyphens, ems, ens, semi-colons, demi-semicolons, and parenthesis. They then take it in turns to punctuate a sentence in a creative, but appropriate, manner. Extra points are given for each comma they manage to slip in their sentences.
2) Nervous tic developed by players of 1), above, when they see items such as misplaced apostrophes and the like. If left untreated, it can develop into a sudden spasm or the dreaded collywobbles. (For more on this disease, see our entry on 'Feeling sic')
