There was a croft (today it’s a bothy) near Arrochar called Abyssinia.
Apparently, a man named Iain Mór (Big John) visited Abyssinia (Ethiopia), perhaps as a soldier, and wouldn’t shut up about it when he got back to Scotland. His friends started calling him “Abyssinia” to tease him and the nickname stuck.
“A’m awa tae Argyll for the day, Abyssinia!”
“No ye’ll no, A’m no leavin Glesca”
