lake licenoun.
Pejorative name given to motorized personal watercraft, such as Jet Skis and SeaDoos.
Example Citation:
"Jet Ski is actually Kawasaki's trademarked name for its models, but most people use the name for all such machines. Of course lakeshore residents, swimmers, beachgoers and boaters have other names for them and their typically ruthless ridersnames like 'Hell's Angels of the waterways' and 'lake lice.' "
