When a
man has sex with a girl who is lubed up with another
man’s man fat, his penis is now referred to as an 'oaty dunker', because he has stirred another
man’s porridge…
Big Dave, “Oh man, I was with Katie last
night, it was great! What a filth bag”
Little Jonny, “No
way man, me too! I went in straight after you, then afterwards she cleaned my oaty dunker with her mouth. Total
filth!”
