A Sidey
A Sidey is a weak actor from Bombay who plays second fiddle to the main guy. They’re like the weirdo in the class who no one talks to.
That guy in the movie was a total Sidey, just standing there like he didn’t matter.
My friend is a Sidey, he sits in the back and no one even notices him.
She was a Sidey in the play, and everyone laughed at her.
