She is AMAZING! She is the kindest, sweetest, person you will ever meet. She is the absolute best friend. She can be funny, crazy, and weird, and even a complete psycho at times, but always in the best way. If one enters your life never let her go. EVER! She will be your most treasured possession. She may be slightly Anime crazy, but it is what makes her Casse. And her sense of style is unique and she will surprise you with how she can make anything look good. She is the BEST wife of all time.

on se casse 

It means in French, let's leave. Se casser in French really means to break. But in slang, se casser means to leave. On is a familiar way of saying, We. Thus: Let us (we) leave. The se is a grammatical word and this is not a French lesson so let us leave it at that.

Cette boum est morte, on se casse!
This party is dead, let's leave!
This party is dead, let's get the hell out of here.

Voilà la police, on se casse!
There is the police, let's get the hell out of here!
