viking

A person, usually a male, who lives dirty and hardly, if ever cleans his surroundings. When a viking shares a residence they leave things dirty including residues of bodily fluids and other types of crud in common areas of the dwelling. The term became popular in institutional settings after the film "The 13th Warrior" was released in 1999.
