literal translation: your sister's pussy! this sentence in English language is not complete because the adjectival is missing. Howerver, in Arabic it is a complete swear word which means: you are a brother of a whore sister. The closest equivelant in English is Mother fucker kos ommak.

In Arabic culture it is very offensive to mention someones mother in a rude way, let alone his sister. The female members of ones family represent his honour and dignity.

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.
