To feed the tabby is to drink milk and then soon after swirl the milky liquid inside of the vagina until thoroughly satisfied. Or one member passes out.
Typically a British euphemism.
"Fucking hell, mate. She fancied me giving her "tabby" 'a' feeding."
"Pal, her fanny's is rotten enough! Weirdly, I could sense she was the kind for Feeding the tabby."
