A TANGIE is a Scottish legend of a shape shifting sea spirit often found in the form of an old man covered in seaweed; perhaps also an unclean beach dweller or dwellers seen as degraded, ethereal, spiritual or inhuman entities as in The Doors lyrics - Maggie M’Gill:
“Miss Maggie M'Gill she lived on a hill
“Her daddy got drunk and left her the will
“So she went down, down to TANGIE Town
“People down there
“Really like to get it on”
So she went down, down to TANGIE Town
Directly translates to thank you lord, is a person who is humble and loves life even when it doesn't love them back. Persistence and determination are two words used to describe such a person.
