A Horse Cock Sandwhich, AKA HCS, is a chronic liar. some one who will quite hoenstly lie about anything. You could literally ask if they ate lunch and they will go out of their way to lie about it. You don't want to be an HCS or be associated with one. If you are one. change your ways. But you probably don't know you are and if you did. You would like to your self to say your not.
Bill: Man Josh such a Horse Cock Sandwhich.
Tony: He's an HCS?
Bill: Yes man he Horse Cocked me about wrecking his car last weekend.
