One of the medieval Peel towers on the Scottish Borders was at Tinnies.
Colloquially meaning a game in which a group of people jump on top of each other to form a pile, like sardines in a tin. The game is initiated by an individual shouting "Tinnies", then lying face down to allow other players to lie on top, forming the pile. This game is also known by the names "Bundle" or "Pile-on."
"Tinny" is also a term for audio which lacks resonance, resembling a piece of tin being struck.
The phrase is also referenced in the Monty Python sketch "Woody and Tinny Words" where Graham Chapman describes various seemingly-random words as being "tinny" or "woody" with the former utterance inducing great discomfort in his daughter.
In the Scots dialect of the town of Bathgate, West Lothian, "Tinnie" often refers to an aluminium can of Tennent's Lager. "Here Oj, gies a tinnie o'er mate".
