answer:Damn it, Mazingerz…..“spitted out”? Don’t make me come over there. Lol. I also assume those black spots are gum, too. I like chewing gum because I get tense sometimes and I chew the gum to release some of the tension. If it’s not gum, I’m gently chewing on my tongue or clenching my teeth. I don’t litter, though.
