A phrase that can be added on to the end of a statement to make it sound obvious-- implying that the other person is stupid if they didn't know the statement.
Frenemy: So, have you kicked him out yet?
Anne: No...?
Frenemy: What are you waiting for? He'll never change.
Anne: I'm not sure wha--
Frenemy: He's cheating on you, you know that, right?
Anne: Oh! Uh... yeah... I...I uh totally knew that...*cough cough*
