What is the meaning of "or something"? When can I use it?
"Or something" is put at the end of a sentence to refer to another option or listed item which is unspecified, but similar to the one previously listed. You can use "or something" when you aren't certain about one option being true but you don't know any other specific options that you could suggest. Ex: How do you know that I have an allergy? Are you a doctor or something? Ex: His name is Bob or Billy or something.
