"FF" on Twitter means "Follow Friday": Basically it's about promoting an interesting Twitter user and helping them get followers.
To participate, you recommend that people follow someone.
Here's the syntax:
USER_WHO_IS_RECOMMENDING #FF @recommendeduser1 @recommendeduser2 @recommendeduser3
it probably means Follow Friday (this is where people shout-out their friends or whatever in a list every friday) however if it isn't a shout out it could be something else
friends forever
