4chanitus is a condition most prevalent within males aged from mid-teens to mid-twenties. The infected individuals forget the anonymity that should be associated with visiting 4chan, and so use 4chan lingo on social networking sites such as Facebook and Twitter.

In worst case infections the individuals are even prone to using said language in real life.

Worried friend: Sorry what the fuck?
