A person who is so unbelievably hot, fit, gorgeous or has a certain "je nais se quoi" that you feel the sudden urge to literally drop your pants. It could be any where or any one. But it could happen to you, wear your belts people. Deadly.
Firstly derived from an Apple auto correction of "jaw dropper".
