A website where pretty much anyone can make chatboxes, which can be embedded in websites, like irc. Unlike IRC, however, they are known for having a community full of annoying kids, trolls, and being run by Admins who would rather make useless powers then make a proper mobile client.

Also has an annoying LinkValidator, which is supposed to prevent phishing yet blocks too many links in chats.
Average XAT user:
"Dude ur chat sux lulul"

"I need powerz plz"
