Somebody who has superb banter and is really, really cool.
Darwin: "Like, OMG Alice, have you seen that guy over there? He's so bantercool!!"

Alice: " I know right, he's super cool and full of banter."

Attenborough: "I agree guys, he is definitely, what I would biologically describe as being, bantercool."
(If David Attenborough and Charles Darwin think you have evolved to be one of the rare specimens of Bantercool then you are amazing and all known as Alice worldwide, especially those residing in Romford, will from this day forward refer to you a bantercool.)
