While performing oral sex on a female partner who is wearing an outwardly sharp clitoral ring or piercing, a man will give her vaginal pleasure with his tongue while the woman pushes his face towards her pelvis in order to thrust his tongue deeper into her vagina. Then she decides to be a cunt and thrust the poor mans face into her clitoris so that her ring or piercing will cut his forehead. Thus, he will have received the Harry Twatter because of the Harry Potter like scar on his forehead.
A twatterpot is someone who rages so incredibly hard that they start raging at things not related to the original cause of anger

Bob: Dude don't be a twatterpot.
