Basically, a facial hair feature that resembles a Hitler mustache that migrated south, but otherwise having little to no relation to the genocidal fascist dictator, and not at all necessarily bad or evil. Opinions upon the soul patch can vary widely from person to person. Contrary to popular belief, it doesn't necessarily have to mean or indicate anything.
Woman 1: "Why are you dating that creep? He's got that weird tuft of hair below his lower lip..."*shudders*
Woman 2: "I actually think the whole soul patch thing is kinda sexy."
I wouldn't be caught dead, dying, or undead wearing that stupid square "soul patch" crap above my chin.
A person questioning their sexuality who uses a same sex openly gay friend to have a pseudo-relationship with. They flirt with, question, and faux date their gay friend under the guise of friends hanging out.
It doesn't cover up as much as a full beard, and most people can see what's going on underneath.
My best friend asked me to the movies and asked me how I "knew" I was sexually attracted to women, I think I am her soul patch.
My friend insists we hang out everyday, when I told him I was too busy he acted like I broke up with him. I think I am his soul patch.
