Yeah it just means fool I guess, it's an old word that even my grandmother used to use! Not to be confused with the alternative spelling - the letter I replaced with an a is probably the one you have in mind, which I imagine falls foul of the censor lol!Is the original English version not rude enough? From here, I really wonder how 'twitter' ever became such a popular platform...
But 'twit' isn't censored by this forum. Strange.
