insanity. An ideal forum for internet tough guys, pretentious bitches, would be political pundits, old women and shitty poets to sound off. Members of the '

2. A place for douche bags too old for
4chan to hang out.
3. A web browser utility used for trading kittens photographs, smut, and astronomical photos amongst 'friends', who are generally
people you wouldn't spend a minute with in real life.
