Based on the Netflix show 'Big Mouth' it is the verb to describe the act of being big mouthed. While a friend stays over at his comrades house and he decides to masturbate during the night, this is described as 'big mouthing'.
Daniel: "what are you doing Finn?! Are you big mouthing me?!"
Finn: "Yeah.. sorry I just got really horny.."
Finn: "Yeah.. sorry I just got really horny.."
