The way I heard it yonks ago a "weasel" is some gadget used for ironing clothes *** and to "pop" is to pawn.

***This makes the "The Cotton Row" line seem more logical although I have also been told that "Cotton Row" was a street in London

When my Dad was a boy they used to sing...

Every time your Mother goes out
The monkey's on the table
Get a stick and Knock him down
Bang goes your umble.

I have never been able to figure out what the last line of that meant either.
