My friend from the Philippines told me about this one. I always called it a Philipino holster.There is a style of carry that uses a piece of cord, like a shoe lace, which is tied at the ends to form a circle. It is then looped under the belt and back though itself. The handgun is then put though the loop and inside the waistband. The idea is that it is a bit more stable than Mexican but than the gun can be ditched and the "holster" can be discarded or simply ignored. I cannot remember what it is called.
Origion? Who knows.
