How do you say FABO?

FABO
Fay Bo
Fay Bow
Fahbo
Fab Oh


It honestly doesn't matter. we all spell it FABO, lol.

Another example:
Do you pronounce the "t" in often or do you say "offen". On the net, it really doesn't matter, because no matter how you pronounce it, you still spell it the same way, and that's what is important on the 'net, anyway. ;)
