Win a Motza
It's an old-generation word!
"Mozzer, mozza - luck, good fortune.
This seems to be the main surviving variant among many words (‘mozz’, ‘mozzle, ‘mozzy’) deriving from the Yiddish
mazel: a cooke blessing the consumer with good luck. The words have existed in British working-class speech since at least the 1880s and later became part of Austrlian usage, usually in the forms motzer or motza."
