When you start to crush on someone because they like you. Much like Rachel falling in love with Ross after finding out he has a HUGE crush on her.
"I think I like him."
"No you don't, it's just Rachel Green Syndrome, it'll pass."
Someone who is very spoiled and ditsy and cries until they get what they want
Rachel Green: Isnβt that just kick you in the crutch spit on your neck fantastic?
Everyone else: wtf is she saying?
Random guy: lol, she just has a bad case of Rachel Green Syndrome
