Well, in that case, I just ended my own game in the first go :P (that’s supposed to be an ‘n’ not a ‘so’ – guess I hit the auto-complete a little too soon, or just without noticing the difference haha).
So my go was supposed to be ノーパン, which ends the game and someone else goes.
Hang on, んです is in the dictionary; surely that counts as a word beginning with ん? :D
