What is the slang word given to left handed people?

There isn't a widely accepted slang term for left-handed people. Some people use "southpaw" to refer to left-handed people, especially in sports, but it's not considered a true slang term.

It's important to note that using slang terms to describe people based on their handedness can be seen as disrespectful and potentially offensive. It's best to use respectful and inclusive language when referring to people.
