Black Thumb

Definition:

A Black Thumb is the male equivalent of a black widow. It's a toxic, narcissistic man who is poisonous to everyone he encounters, much like Henry the VIII. His heart is as black as the underworld and he's as attractive as a thumb - hence, black thumb.

Exemplification of Usage:

Her: Are you still dating Killian?

Me: That guy is a black thumb, I'm embarrassed I ever dated him.
