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)

Stealthie 

when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.

This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
