Tribe of Native Americans that originated in what is now East LA. Legend has it that they were christened into manhood by pouring the blood of a bear they had to kill with their bare hands onto their palms, rearing back, and lettin' the local Injun whore have it...SLAP. Also were known for their unusually large right hands.

Ron: It must have been from the Slapahoe tribe
