shoutout to rui for attempting to work on his banter game you'll get there one day buddy! Practice makes perfect
Banter is generally regarded as public good as one's reception of it does not impede another's, and the supplier cannot reject other parties seeking extra benefit from it. However, to varying extents one may view it as a club good as the non-excludable assumption can be violated depending on how it is defined. One possible way this can occur is the selection of whom to inflict banter upon, and completely rejecting the existence of another party.
Banter is also subject to generating both positive and negative externalities. Depending on the level of offensiveness implied in the banter, another may attain negative benefit, but if the implied humour is effective, it probably allows others to laugh as well, which can be reflected through upvotes and haha reacts especially on social media.
The market for banter is perhaps, more accurately considered an oligopoly as there are various suppliers, but fails to be perfect competition as at any given point, one's supply can dominate over the other and vice versa. It may be worth noting that cartelisation is uncommon as people are very much capable of producing their banter.
And that, my friends, is how to economics.
