Roastburger 

Arby's burger done better. Never greasy and never fried. All your favorite burger toppings on thinly sliced roast beef with special seasoning and sauces.

I am heading to Arby's for a All American Roastburger!

Ratburger 

Any of a suite of dodgy meat products purchased from a mobile eatery (e.g. a kebab van owned by a man called Stelios) often found in car parks within close proximity to nightclubs.

I feel dead rough this morning. I think it must be that filthy ratburger I got from "Kebab Ye" on the way home from "Shades" last night.

Roostburger 

While on a dirt bike, hold front brake and pull the throttle. This makes dirt shoot out from under your back tire.

That was a fat roostburger, bro!
