Light Sabering 

The act of swordfighting, with the addition of a bendy glowstick shoved in the urethra while the lights are off.

We were swordfighting, but the lights went out, so we tried Light Sabering instead!

Sideræl 

si:`dəræ:L

Sideræl (from Norwegian "side" (side) and "ræl" (scrap, something of low quality). It could be anything of low quality laying on the side, usually worthless.

In 2022, Elon Musk and Grimes named their son "Exa Dark Sideræl". An unfortunate choice since this is not a positive word.

The salad on the kebab plate is just sideræl.

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)
