Long ago when the world was young BBC Scotland produced Stanley Baxter (a Scottish comedy actor) in his own show which included a section entitled Parliamo Glesgae, a spoof on a typical 60s language learning TV show.
This is the only Glasgow saying I remember from the show, and the reason for that is the very memorable phrase that was used to illustrate its meaning: erra rerra perra doos.
Imagine two young men on Sauchiehall Street in Glasgow lasciviouslyeying the figures of young women as they pass by. When a particularly well endowed woman goes past one friend nudges the other and mutters erra rerra perra doos--there is a rare pair of boobs (I suppose you might render the word doos in this way).
Really Stanley Baxter was just making fun of the Glasgow accent.
