Ebrow is a movement of the eyebrows in a suggestive manor.
It could be perhaps used to seduce someone particularly over the internet.
It can also be used to describe someones sex appeal.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.
