Bigger Luke, commonly abbreviated to BL, or more uncommonly BgL, is the slightly larger manifestation of Luke Skywalker that is said to appear in certain scenes of the original Star Wars Trilogy, contrasting to Regular Luke.
The appearance of Bigger Luke in a particular scene is generally, but not always, judged relative to the height of Han Solo, and as such Han is the primary go-to frame of reference amongst Bigger Luke Theorists. Because of this, "No Han Pics"(commonly abbreviated to NHP) are generally discouraged, as it is very difficult to determine Luke's height without Han Solo as a constant frame of reference.
Who knows? Maybe in the next one my part will be twice as big. https://t.co/9UeEYr7Wzr
