Seems that Puerto Rico uses the verb reyar to describe the action of leaving group in pursuit of aguinaldo, and could derive from such action. In any case, may have been a mistake and instead of reya was meant to stripe, which is having several meanings or uses. For example, it is a fine or thin line formed naturally or that can be drawn on a paper and other materials by hand. Likewise, it is the line that can be drawn to dry our hair or is the name used to refer to the aquatic animal, manta ray.
