A day of celebration of one's birth. Invented by a child, used by adults because it is just better to be birfed than birthed.
Because, it's your birfday and you can say it anyway you want too.
Yo' Happy Birfday, man.
Go girl, it's your Birfday!

It is now used on the Internet and everywhere instead of the actual word 'Birthday'
I guess they say it cause it sounds better
