I think the "vowel sound" they refer to is best expressed as a "w". Apparently, even the queen mispronounces the "l" in "milk" as "miwk". As for rhyming slang, weegie rhyming slang > cockney rhyming slang Cannae beat hitting a Des O'Connor

Oh here we go again. Glasgow this, Glasgow that. Did you know that God is a Glaswegian. Glaswegians have been running the world since day one. They are the pyoor dead funniest ****s on the earth by ra way but, but.......................ad nauseum. Glaswegians are smelly, ignorant hygenically challenged ****buckets who inhabit the smelliest and most dumpish city in the world. There, I said what all non weegies were thinking.
