When someone or something is the best or close to it. Sometimes someone can think there this but are not. For example a person with a nice new hair cut who is still fugly but think there all that.See the dogs bollocks or bees knees or all that and a bag of chips.The cat’s meow is a fairly uncreative alternative to the dogs’ bollocks when children are in the room.
person 1 "that shot was the dogs bollocks"
unnoticed child "what?"
person 1 "oh erm the cats meow"
When you are making love to your partner and her pussy lips vibrate against each other making a farting noise. Commonly known as purring. Not to be confused with queefing.
I was pounding away on Sally when she started making The Cats Meow unintentionally. Yeah I made that shit Purr.
