"Never mind the pollack" was the headline of a report on Sky News about Sainsbury's renaming a type of fish.  The traditional English name of the fish is pollack, but they've decided to name it colin (pronounced co-lan), the French word for hake, because customers are too embarrassed to ask for it, although why on earth they would be embarrassed is anyone's guess, as long as you pronounce it correctly it doesn't sound anything like @#*!!@#@.  The headline is a play on "infamous punk album "Never Mind the @#*!!@#@ Here's the Sex Pistols."

It's all a load of pollacks to me.
