Noob question :(

What's a BnB combo?? or what does BnB stands for??

[F9|Chibi]

BnB stands for Bread and Butter. It's a term used to describe the 'target' combo your character has without the need of meter / situations / set-ups, otherwise.

As a simple example, if you land a standing A or crouching A on an opponent with Warc then you can do 2b, 2c, 5c, j.B (2 hits), j.C, j.B (2 hits), j.C, air throw. That's her bread and butter, or BnB.

It's just a basic combo that you can go into easily.  It usually doesn't involve using meter, but there are exceptions.  Most start with 2a with having the option of a jump-in before it.
