Sinistaire 

A sinistaire is a fictional character that's predominantly left handed. Lefties will usually point them out if they ever see them.

Ashley: Look, Sara! That character is left handed!
Sara: So they are a sinistaire.

Sinistar 

A mid-1980s arcade game where you pilot a ship through an asteroid field mining for bombs to use against a super-demonic space robot called Sinistar, which is being built by swarming drones and defended by fast-firing tanks. Once Sinistar's construction is completed, he starts threatening and taunting you ("Run, Coward!") and makes a beeline to your sorry hide. The stress level involved gets ridiculously high. It is/was quite possibly the toughest arcade game in human history.

Beware, I live.
I hunger.
AAAAAAAURRRRRRRRGGHHHAAAAAAA!!!

Sinastare 

To maintain eye contact and friendly banter with an acquaintance whilst mentally performing outrages sexual acts.

While the conversation was friendly enough, when she mentioned her daughter’s netball team, he returned a smile and a Sinastare that sent a shiver down her spine. “I think I’m going to go,” she said. Zed smiled again and said nothing.
