Nowadays used in a passive aggressive way (usually by the british) at school or somewhere public when someone tries to act big and bad or naughty when they're really just a try hard.
For example:
Person 1: Talk shit about me one time and I'll batter you - you hear me?
Person 2: Ooh, sorry roadman - I'm so scared - shiver me timbers!
An infinite consequence of drinking Sherry. Even if only consumed once it will haunt you till your death. Causes unannounced shivers occasionally throughout your life.
Ben: Tom, how are you cold? It's the middle of July!
Tom: I'm not it was just a Sherry Shiver. Ben: Those things are whack!
Those characteristic moves first launched upon the awestruck world by the woman who has music in every part of her body, Tina Turner.
I watched the artist do her own version of the Tina Turner Shivers as every muscle in her face and body pulsed to the music as if it was running in her bloodstream!
