Same Fanbase Factor is the generally-accepted theory that in matches involving two characters that share the same fanbase, the results will be somewhat skewed in favor of the more popular of the choices. Most matches involving two Square, Nintendo or Sega characters are said to have some degree of SFF. SFF is also sometimes called the Something Fishy Factor, to make light of the fact that whenever anything the least bit odd happens in a poll, the Stats Topic will attribute the oddity to some kind of SFF without hesitation (eg "this must be RPG SFF" or "clearly he's getting PSX-SFFed here").
