The Britanic sank in ww1 by a mine. And the Olimpic is in a privately owned dock owened by some random millionaire

Little sister

A really fucking annoying person that is someone's younger sibling and is a girl at the same time. Usually annoys the shit out of their older sibling and the older sibling's friends.

Boy1: Holy shit, your sister is so fucking annoying.
Boy2: I know right? I wish I didn't have a little sister.
Boy1: Yeah, she always walks in on us when we're playing games and she never fucking leaves us alone.

little sister syndrome

when a girl feels like she annoys everyone she talks too, the fear of being seen as an irritating burden

Sarah has an awful case of little sister syndrome, she wont tell me what’s going on
