If someone looks like there about take a shit when saying a word, it’s the real deal. When someone just moves there mouth using a repetition without any other facial expression there tryna flex stuttering. Key - every time I wold stutter I’d always look away from the person to try and grab a hold of myself, get some composure, concentrate on the word. Something about staring into another persons eyes while stuttering makes me feel like ashamed or not good enough. It sucks but I shrug it off and get them next time eh
