Bag the Neck

When someones fit is looking trash, neckline looking baggy, insult to describe someone who "bag the neck" means they are trashy

1: do you like my new kicks?
2: nah, bag the neck

Sog the Bun

Something that is a bit rubbish, like when your bread bun gets soggy from too much sauce and falls apart.

1: Do you want to go out tonight?
2: Nah, sog the bun on that
