Lucas Etter's method for the Rubik's Cube is CFOP (the Fridrich Method), but Lucas sometimes uses a last layer variation, which is called COLL. COLL is doing OLL and putting the corners in the right place in one Algorithm, which increases the chance of a PLL skip. This can only be applied when the last layer edges are oriented.
