A term used to describe a place that
is rumored to exist but conclusive evidence
justifying its existence has not been
found. Often it is used when people get lost while looking
for a place
they cannot find.
Etymology: The term comes from the supposed location of the alien bodies
found at Roswell. It is thought to be somewhere in New Mexico and is highly protected by the government. The mantis
band, Megadeath wrote a song about "Hanger 18".
"On our way to the Pottery
Barn, we looked everywhere for East Lyman
Street but I think it was a Hanger 18. Instead, we took
a different route."
