boy howdy

1. An exclamation most typically used by those exposed to (and not utterly embarrassed by) southern culture. It is, in essence, the southern version of the urban expression 'girl bye'. When spoken sarcastically, it is used to render a thing ridiculous or label it unimportant. When spoken sincerely, it is similar to the expression 'hot dog!' and implies that a thing is impressive, pleasantly surprising, intriguing or a combination of the three. 2. An anatomical orifice used in the act of sex, such as a woman's vagina or a person's anus. The mouth is not typically referred to as a 'boy howdy,' though it, too, fits this description.
