Think bimbo, but actually better.

He's a little slow, but he's trying his best. Big, beefy, almost always has a nice ass and drinks respect women juice. Most of the time the only thing playing in his brain is elevator music.
Just don't make him think to hard and you should be good.

A man who generally is stupid, but tries hard to be a respectful man.

Like Fred from Scooby Doo.

See bimbo

Generally, a large (broad, tall, or buff) attractive man, who tends to be not very bright, but usually extremely nice and respectful. Think Kronk from The Emperors New Groove, or maybe a golden retriever.

a golden retriever type guy, respectful and not manipulative

male version of a bimbo. They are usually easy on the eyes but spend more time flexing then using their noggin. If your man's self image is tied into his muscles, level of tan, and body hair distribution...he may be a himbo. If he pouts, makes awkward "sexy" poses, and speaks in third person take a picture you may have spotted a himbo

a himbo is a very dumb man with a heart of gold. a himbo MUST be beefy, stupid, and handsome.

h - heart
i - intellect
m - man (a female himbo is a shimbo/herbo)
b - beef
o - of gold
