a friend of Dorothy's
A gay guy. Because Dorothy was the best, and also kind of a mess, so everyone who liked her ended up liking themselves too.
'He said, 'I’m a friend of Dorothy, and I’m not afraid to be one.'
'At the party, she said, 'I’m a friend of Dorothy, and I’m here to dance.'
'He whispered, 'I’m a friend of Dorothy, and I’ve been one for years.'
