When a woman puts tooth paste on a man's dick and brushes it with a toothbrush. After this she puts the penis in her mouth and the paste makes her look like she's foaming at the mouth, like if she had rabies.
A Cumbernauld Sausage is like a Cumberland Sausage, but made by an unemployed scumbag living on the streets. It is full of dirt and looks like something dumped inside the Cumbernauld Town Centre. Popular with homeless people in that area, but universally hated in other towns.
That random burning feeling you get in your dick, usually after wanking and taking a piss too close together.
Frank: "Are you okay bro? You look like your in a bit of pain". Tom: "Nah i'm fine man, just got a bit of a burnt sausage". Frank: "Oh fuck, I hate it when I get those".
