Fartboat

Fartboat (noun)
Pronunciation: /ˈfärt-ˌbōt/

A term for a boat in which one or more individuals continuously emit loud, disruptive flatulent sounds while traveling down a river or waterway. These sounds are often so frequent and noticeable that they disturb nearby boats and passengers.

As the fartboat cruised past, its passengers' uncontrollable flatulence created a cacophony of sounds that sent nearby kayakers paddling quickly to escape the overwhelming stench and noise.
