Psychological douchebag move. When someone purports to know something about your personality or ~who you really are~, and uses this information to be a total dick.
Douchebag: You keep looking down, and you're punctuating your sentences with 'like's and 'um's. I can tell you're a nervous person, especially around people of the opposite gender.
Girl: God, I can't believe you're pulling a fraklin on me.
