Tapibakigrafo

A tong-twister word that doesn't mean anything, but sounds like an old type of type writer machine, or something like that. The idea is to tell this word to someone and expect them to repeat it after listening for the first time, without miss spelling it.

ok... I know this word and lets see if you can repeat it!
"Tapibakigrafo!"

Usually what it comes is:
Tafifagrifafo
Tapipapifrago
Tafrigrafrifafo
and so on...
