TTFN is a "pointless" initialism (no easier to
say than the phrase on which it was
based) meaning "Ta ta for now!"
This
phase is used as an informal parting phrase, as a possible substitute for "See you later!" or "Goodbye for now!"
Rabbit "
Well Tigger if you must..."
Tigger "Ha ho ha haw... TTFN, Ta Ta For Now!!! HO ho ho ha ha!!!"
*Tigger bounces out of door before loudly slamming it.*
