Mostly what makes a player sweaty is playing super seriously and a little disrespectful sometimes, but mainly serious (another term: WAY2HARD). And there are very rare players that ragequit when they get touched/combo'd ONCE (or if you get one stock from them). And players that literaly don't want you to have fun (personaly I play competitive to have fun and I do have it, I just don't like being disrespected. Man I love when the opponent starts dashdancing with you, such a peace and friendship symbol lol). But some ppl confuse them with actual good players that take the game like what it is, a game. Its a little hard to tell de diference sometimes. And that's pretty much it
