a common term used in online video games when one team has a numerical advantage of atleast two extra playersover the other

when "teams" is called out, players should view the number of players for each team and make them even by switching or spectating

Being a team means being committed to something and sticking to it. It means even when you feel sick, depressed, or you have plans, you still participate and stay committed. No skipping. No 'Wahh, I don't fell good." No "I'd rather hang out with my boyfriend." All in all, TEAM means staying committed, showing up even when you don't want to, and giving all you've got. If you aren't willing to do that, they don't bother being part of a team.
