An annoying Personal Watercraft ((PWC) Jet Ski, WaveRunner, Sea-Doo) that uses your wake at a too close proximity to the stern of your boat.
Get the potato gun, we have a swarm of water parasites at our stern.

This lake would be great if we didn't have to hear the whining engines of those water parasites.
