A sexual technique where the woman lies on her back and the gentleman squats over her face while lowering his scrotum into her mouth. The gentleman must simultaneously shimmy his penis back and forth as if to simulate a rat's tail. The gentleman must also lower his hairy anus onto the woman's nose. For those who go the extra mile one can imitate a rat's gnawing sneer.
Rishbah: I was going to break up with her last night but then she let me hit her with the "dirty rat".
