An exclamation of enthusiastic agreement which can be used in both a genuine or sarcastic tone. In addition can used to add emphasis to a statement, much like the word fuck can.

Boy Howdy was also the name of an American country music band from the 1990’s. The term has not direct link or reference to them however.

1. Expression similar to "Oh, gosh".

2. Expression meaning "Oh, gosh, I'm a hick". If you can use "boy howdy" in a sentence with a straight face, you're about as far out of the urban mainstream as I can imagine.

Get the boy howdy mug.
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.
Examples include the term 'boy howdy' in snippets of hypothetical conversation, and should be imagined or read aloud in a southern accent.

Boy me & Rick went down to the crick last yesterday and just guess what we saw!

2.

Condom or nothing, Rick. Make your choice. I don't care if they're not fun, I'll TELL you what's not fun. Growing a whole goddamn person inside you for nine months and then having to push the gaddamn thing out of your boy howdy. I mean it. Condoms or gtfo.
