A term invented by ACR0 and used in his song title, meaning a girl that plays with a guy's heart, and leaves him in misery.
“She was flirting with me but it was an act this whole time” “Damn bro she’s a heart demon”
"She made me think we had a connection, but it was because she liked getting attention from other guys."
ACR0: "my heart is a toy for these girls hmm, a girl is a gun shot me in my heart hmm"
