Freaky Sex with a hamster, or someone that resembles one. It usually includes various positions with hamster porn in the background, lots of squealing and some fur pulling. Usually does not include foreplay, or similar. Most of the time they include tards, animals, strobe lights

"Ya fockin' hamsta brain, you smoked the last smoke and the fockin' store's closed, eh."
"That fockin' hamsta brain, he knocked up Shelley AGAIN."
