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
