When someone sherrises something, they take it without asking and without permission.
Sherrising is not good. It is like stealing.
Examples:
He sherrises the toy from his friend.
She sherrises the cookie from the jar.
The cat sherrises the fish from the bowl.
The bird sherrises the shiny thing from the tree.
He sherrises the idea from his brother.
She sherrises the book from the shelf.
