Shawinigan Handshake 

Shawinigan Handshake is the epithet given to a chokehold executed on February 15, 1996 by Jean Chrétien, then Prime Minister of Canada, on anti-poverty protester Bill Clennett. The phrase comes from Chrétien's birthplace of Shawinigan, Quebec, as the former prime minister often styled himself the "little guy from Shawinigan".

"Yesterday I won the fucking lottery so I shat on my bosses desk then gave him the Shawinigan Handshake."

"Margret is soooooo annoying during meetings. Sometimes I just want to give her the ole' Shawinigan Handshake."

Shirin 

The most beautiful girl you will ever meet. They are one of the most sexiest girls out there. They know how to party and have the best dance moves. They do not know how beautiful they are, and don't believe when people say it. She is shy at first, but once you get to know her she will lighten up your every single day. They make the best girlfriend ever. They are the type of girl that doesn't freak out over little things, unless they are positive. They are very understanding but are not afraid to stand up for themselves. They make the best friends and they know how to keep a long relationship. If you are lucky enough to meet a Shirin, hold on to her because you will never find anyone that is as trustworthy and kind as her.

Boy 1 : damn look at that girl!
Boy 2: she must be Shirin

Shining Force 

A relatively niche strategy RPG series which was among the first Sega console titles to sell over a million copies. Lesser known in the western world, but nonetheless has a dedicated following.
The Shining Force series is a subseries of the "Shining Series", which includes other styles of RPG, and yet maintains story consistency/crossovers throughout the original titles.
Recent additions to the series have not been so well received, but nonetheless the series is alive and growing in popularity as always.

Shining Force is great!
