What does DEFO mean or stand for ?
DEFO is used when we chat online to say definitely with assertiveness and surety. It is one of the oldest short forms and is also used when we talk vocally in everyday conversations to tell the other person to count on you.
There are other acronyms also that mean the same thing as DEFO,like – for sure – FOSHO.
