A white person, as called by a black Jamaican. Also means the blood from a woman's period. Think of it as the Jamican version of cracker.
Bumbaclot is the more friendly version.
Raasclot is the more offensive version.
Jamican guy to a white guy: Yes Bloodclot, whatta gwan?
Me before I knew what it meant: (wow i'm getting called a cool name that sound's pretty 'street' that means this guy must think I'm cool too!)
