To be obsessively and compulsively changinging any font in anything on the internet for no particular reason other than to "Try something different"
I.e:
Myspace
MSN
Facebook
Etc.

Most cases of Fontaculosis results in the infected getting confused with which writing is which, as they regularly forget which font was theirs.
Example for Fontaculosis:

Tom: Lol yeah I thought so. (Crazy rainbow font with Italics and underline)

Bradly: Who the hell is writing this, stop changing your font man, I can't even understand it, and its a bad font. You're not cool, give up you noob.

Tom: Oh.. I see.. (Plain black Times New Roman)

Bradly: You fail. Get checked for Fontaculosis.
