In Korean cuisine, pork belly meat without the skin is known as "samgyeop-sal" (), while pork belly meat with the skin on is known as "ogyeop-sal" (). The literal meaning of "samgyeop-sal" is "three-layered meat" as "sam" (; ) means "three", "gyeop" () means "layer", and "sal" () means "flesh", referring to what appears to be three layers that are visible in the meat. The word "o" (; ) in "ogyeop-sal" means "five", referring to the five-layered pork belly meat with the skin-on.
