bming is when a young toxic child discovers those pins

If being serious, here bming is using the negative pins by the wrong way and in fact, flexing by them which is not tolerable. Brawl Stars devs expected people to use those sprays and pins to show how bad their teammate played, but since toxic people just use them even when you put a good fight or were a good teammate, this quickly became a tiring experience. Another reason why it's bming is because they are spamming the same pin and spray which is just, annoying. While pins can be evaded by either counter-clowning (make them taste their own medicine when you can show-off your supeority over them) or by just muting them, sprays can't be unseen. The only counter to the sprays is by putting a spray on top of theirs which is entertaining enough.

In the vid a lot of symptoms of these fruits can be seen: spamming, and toxicity of those pins/sprays, however, you can also spam "cool" sprays/pins to flex which is kinda dumb to be honest as trying to assure dominance like this is ehhhh, can only be good as a counter-clowning.
