Like Sisters
Any duo of girls (they usually come in pairs) that say "Like" almost every other word. No matter what the conversation or context, or who they're talking to. Most often found together at school or elsewhere, they can't seem to kick this annoying habit of theirs. They are most often just friends and usually aren't, but can be, literal sisters.
i like your sister
Used in speech when talking to some ugly girl, but their sister is hawt. Only use this when the ugly girl is making advances on you.
Treat your girlfriend like your sister
"Treating your girlfriend like your sister" When one treats his girlfriend as he would treat his sister with care and respect!
