APB is a method that efficiently solves EO plus the final 1x2x3 after a 2x2x3 is built. The idea came from thinking that more should be done during the edge orientation step of the Petrus method. So in APB the first step is to solve the 2x2x3. After the 2x2x3 is built, solve one of the F2L pairs while orienting all remaining edges. Then, solve the last three pieces of the F2L. Finally, solve the last layer
APB stands for Athefre('s) Pair & Block. Thanks to Ryan "OreKehStrah" Hudgens for the initial name idea to create the acronym and Melkor for the word Pair to more accurately describe the method.
