this phrase is derived from the fable by an acient guy called aesop

the story is that a fox sees some grapes high up0n a tree, he tries to get them,but after many failed attempts,the fox walks aways and says "they are probably sour anyway"

when somebody says "thats sour grapes" they are talkign about somebody desiring something,but unable to have it,so they pretend like they dont want it.when infact they do!
guy1 (who is blonde) : wow that girl is fit
guy2: dude she h8s blonde guys!
guy1: oh i dont care she is probably a dyke anyway

Get the sour grapes mug.
A term used to describe why some people hate others. Originating from a classic novel, sour grapes has adapted to being a frequent term used when one can’t get the fruit (beautiful girl, great job, significant money) and so they discredit crucify and condemn it to feel better.
