Person who for some inextricable reason attracts bad things and events to happen to them.

Any person, in which trouble and drama, follows them everywhere they go.

Used in EMS and ER settings. Things are rolling along smoothly until a certain person arrives, then all the weird calls start or we get extremely busy. That person is the Shit Magnet. Most Shit Magnets already are aware of their condition to attract
problems for everyone or the entire department or crew.

Someone who for some inextricable reason attracts unpredictable and interesting events. Someone who finds trouble and likes it.

Someone who is full of shit.
