When you get mad at someone (typically a partner) and instinctively start stabbing them while screaming curse words at them (hence the name).
"Dude I'm in some deep shit, I accidentally slurced my girlfriend! You gotta bail me out bro!"
"My uncle slurced my aunt in front of me when I was a little boy."
Pretty much another word for blood, but specifically the blood that comes from a person who was slurced (stabbed by their partner during a heated argument). Some say it has a pungent aura.
"Yo, my plug said he's selling slurce juice now. I really gotta find a new guy"
