sivel 

The brown skid mark in white underwear that somehow creates balance and golf swing tempo for a high flight draw and/or chip ins around the green.

Tiger Woods needs more Sivel to regain his form.

Sivel 

To live civilly with the ability to side with evil to overcome the evil imbalances in society.

"Sir, they robbed us of our food and took our supplies needed to survive."

"Then they have 1 day to return what is left and I will grant them 1 additional day to recover what has been used. If they can not meet these demands, we will deal with this in a sivelized manner."

Shivelights 

Sharp rays of bright sunshine that pierce the canopy of a wood or forest. The word possibly owes part of its origin to shiv slang for a knife which in turn is derived from the Romany word chiv meaning a blade

Those shivelights are so bright they hurt my eyes

sideload

To download a file, esp. an application, to a smartphone or other electronic device outside of the accepted or usual channels.

The app center says the eBay app isn't available yet for the new OS on my phone, so I had to sideload an earlier version from a Dropbox link I found.

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)
