Royallie
A royal wank. Rubbing one out on the sly with the protection of a love rubber.
Me: "What the fuck, there's a spunked up jimmy hat on the back seat!"
Stapo: "Yeah Chin.E was having a royallie back there"
Me: "What's a royallie?
Stapo: "A royal wank, its when you tarp up & rub one out, keeps the sheets tidy"
