Literally the dogs testicles. In
British slang, bollocks, means "testicles", however, when it is applied in this context its usual and derivative meaning is "the best", or "
the greatest", or "superb"
interchangeable with the expression "the mutts nuts"
usually is applied in a similar fashion to: "That jacket is
the dogs bollocks as far as I'm concerned"
or "when are you having
the dogs bollocks lopped off"?
A Television chef might stir the pan, taste the contents, and then look into camera while saying,
"You know, these
Korean meatballs REALLY ARE the dogs bollocks"
