Tips the Tuna 

A term used in place of, “gaining in popularity” or “attaining critical mass”. The term is an antonym of “jumping the shark” (a term for something that has outlived its initial popularity or usefulness).

Have you tried that new service from Google. It tips the tuna. Unlike IQC, which no one uses.
