I've recently discovered and been amused by
autocomplete me, a site which collects some of the more random sentiments expressed through google's autocomplete thingy. This afternoon I invented a game of my own - typing obscure words in to the search bar and trying to find ones where it has no suggestions. It only counts for single, real words (no phrases or gibberish). It's actually surprisingly hard - you're looking for things which are obscure but by no means exotic, so no-one would ever look them up.
So far, the only ones I've found are the nasty shade of reddish-brown which is
puce, and the humble
strimmer.
