Townies think it is the most feared insult in the world or a reply to everything. A common response if a townie says 'ya mum' is to laugh.

A really lame comeback, for people who can't think of a decent one in time. Was very popular for a time, but now has died down. These comebacks are related to the "Yo Mama" jokes which are just as bad.
Person 1 - Go fuck yourself.
Person 2 - Ya mum...ummm...yeah! Ya mum fucks herself, hahaha wasn't that awesome guys, Burn Person 1!
