Al Pastor translates to "shepherd style" a reference to the Lebanese immigrants that came to Mexico and brought with them lamb shawarma–cooked on a vertical spit. Traditionally, tacos al pastor are made up of thin slices of pork shoulder, marinated in a combination of different spices and dried chilis, then slow-roasted on a rotating spit with fresh pineapple at the top. Tacos al pastor are often referred to colloquially as "al pastor" or even just "pastor".
