You know what I mean. These are the things that are done randomly by someone and subsequently reproduced in mass amounts for a given amount of time. Some are fun, all are fads. Here are some that I noticed.
*posting your "family" in your sig
*fantags (ie Maru Fan buttons)
*writing "'nuff said" at the end of a post
*using images in a reply post
*quoting someone, changing what they said, and saying "fixed it for ya"
*putting random crap in the edit comments
*posting which thread inspired another in the OP
