Actually supposed to be pronounced 'see-saw' in reference to a the play ground equipment. However, this is a cute way of saying it. Its a term of endearment for someone who balances your personal see-saw or she-shore for you. you're better half. can be your best friend, your sibling or someone close to you who is beyond awesome.
