Cardi B's new and improved 'OK'
So I heard Jennifer hudson do it, Miley Cyrus do it and went "Is this a thing?!?" The answer is yes, yes it is!
Cardi B is being credited for it the new, improved super cool way of saying "OK"!
For me its another reminder I am no where near cool - I had a crack of making the sound myself and couldn't - must be a singer thing. (she says to make herself feel better.)
