You know I once got the word 'cunt' in boggle. I have a photo somewhere.
God damn it was about 8 years ago.
Also, I made up some great words in Scrabble. You just have to say it confidently and be playing against uneducated bonces. Bit me in the arse when I tried 'qualia' and nobody (not even spell check, it seems) believed me that it is a word.
