what ah?!

i remember a friend told me about a person who unconsciously or consciously snakes out everything and anything she wants.
i haven't gotten the right word to describe it...nor coin a word for the sake of it

but i think it is more like of insecurity...perhaps that person have the wrong notion that if she gets whatever other people want, she'll be step ahead of the others...and the idea of it gives her the sense of feeling up there or successful.
