Mums soul

A phrase popularised in Melbourne, Australia meaning to swear on something, or make a promise.

Most often used when trying to convince one of the boys about some crazy story they probably wouldn’t believe.

Example:
“Bro we were up all night going hard and this guy jumps off the balcony and laughs, mums soul”

*Watches horror movie*

“Nah mums soul I would’ve ran straight away”
