Meaning of ちはース


Context: a boy shouts 「 **ちはース** 」 after seeing that a fan club for a boxer
has only female members. He is happy to discover this since he is the kind of
guy that always tries to flirt with pretty girls.

I understand that this is an exclamation expressing surprise, but is it
common? Does it have an exact meaning or it is only onomatopoeic?

Also, is it vulgar? Something like "holy shit", or is it more similar to
"wow"? I am asking this because the character shouting it often speaks in a
vulgar way.
