Eat a mum's potatoes

When you suck on a single mum's arsehole that hard her hemeroids pop out so you give them a chew.

Went to Jenny's last night to eat a mum's potatoes last, they were extra juicy.

Mum-off

To have a verbal contest over progressively worse mum jokes. It usually goes around full circle before someone gets mummed-out.

Kevin: Your mum's a slapper.
Joe: Your mum is a bigger slapper!
Kevin: Your mum invented being a slapper!
Joe: Your mum wrote the slapper's handbook!
Kevin: Your mum followed every move in the handbook!
Joe: Are you challenging me to a mum-off?
Kevin: Your mum likes a challenge... etc
