sibyl fucked

a sexual encounter in which one party exhibits such insane, irrational, or bizarre behavior that the other party is left afraid of further contact

From the movie Sibyl, in which Sally Fields, portraying a victim of multiple personality disorder, has sex with some guy and ends up climbing his bookshelves while claiming to be a succession of different people and speaking in sometimes demonic-sounding voices.

I took her home, and she sibyl fucked me so hard, I ended up getting a restraining order. I still have not replaced the painting she slashed or the couch she shat on.

Younger sibling

A little pest who likes to burst into your room while your doing homework, or playing on your phone. They like to hit you, then like a little bitch, they tell your parents when you hit back. In other words...they are annoying. They are so annoying they make you feel like banging your head against the wall so hard you lose all your brain cells.

You: *on your phone*

Younger sibling: *bursting into your room and runs up to you* Hey!

You: Go away.

Younger sibling: No! *Slaps*

You: *Slaps back*

Younger sibling: ....MOooOOoOoM *ugly sobs*

You: GODDAMNIT *bangs head against the wall*

Sibelius

1) The most prominent (And just about only) Finnish composer. Lived from the late nineteenth century well into the middle of the twentieth. Famous for his seven symphonies, particularly the second and the fifth. Also produced such well known classical pieces as 'Finlandia', Finland's unofficial anthem, Valse Triste', his Violin Concerto, and his choral symphony 'Kullervo'. Although he lived up to 1952, he did not compose any new pieces after approximately 1920.

2) A music notation program known among the musical community for being annoyingly overpriced and very useful at the same time.

Sibelius is the only composer I know who can write music that reduces an entire audience to tears with his music (well, rappers can, but in a different way)
