What is the origin of the waypoint WORUM (neayby Houston)?
It's worm, as in tequila worm:


  Perhaps even more popular than the actual tequila is the worm crawling around the bottom of the bottle. But the worm, or gusano, actually originated with tequila's “lower-quality” cousin, mezcal, largely as a marketing ploy. The gusano is the larvae of a type of moth that lives on the agave plant.—huffingtonpost.com
