Being so fucking hot/beautiful/pretty that every boy has to try to hide his boner and avoid getting a red ass face. Hotness is subjective though.

Where do I begin. If you get called hot af then your name is probably Abby. Abby's are extremely beautiful and caring. They are the hottest in their friend group and many boys want her. if you are the lucky guy to get a Abby then don't lose her. Hot af is equivalent to Abby or Susan straight facts.
Boy 1: God damn that new girl is hot af.
Boy 2: omg ya she is.
Boy 3: I heard her name is Abby.
