Turd Lunger is used to describe a person who derives pleasure from getting a lung full of vapors from a healthy pile of freshly grunted crap. This type of individual will not enter a bathroom without ample reading material, thus not depriving themselves ample time to “Lunger” the vapors.
Turd Lungers are closely related to Turd Linger in that they both enjoy turds; however the Turd Lunger is motivated by vapors whereas the Turd Linger derives pleasure from scent and sound.
