Large Ugly Rock Piece (or LURP) is a large multifaceted element, commonly made in earth tones such as grey, light grey or brown, but sometimes seen in white or even blue, that can be used to model rocks and stones and make it easy to create cliffs and mountains in a very fast way.
Sometimes used interchangeably with Big Ugly Rock Piece (or BURP) many consider the LURP and the BURP to be two distinct elements. Bricklink identifies the LURP as the smaller element, slightly triangular in shape.
There are some Adult Fans of LEGO (AFOLs) who consider the use of LURPs and BURPs to be cheating, that is, they offer the builder something that could be built out of other elements as part of the overall assembly, and thus they are a kind of POOP. Others consider their use to be perfectly legitimate, for aesthetic, convenience, time spent, or other reasons.
LURPs have been found in sets from several themes but especially Castle and Pirates. Some consider these a form of juniorization.
