Yee hah, partners! There are a lot of common slang usages in American English that come from the Wild West cowboy days. I am pretty familiar with them as I grew up in Idaho, one of the most rural states in the USA.
Howdy, Yabla friends. Much of America's history is pioneer history.

"Howdy" comes from shortening "How do you do," and though it originally came from England, it's still commonly used in the American West instead of "hello."
Giddyup! If the supply doesn't meet the demand
Then go out and get more than you will need
Giddyup! If you are tired of playing a losing hand

"Giddyup," also written as "giddyap" and "giddy up", is an expression that comes from a command given to a horse to go faster. It's still used today to mean "let's go" or "hurry up."
This is called a saloon.

A saloon is, as used in British English in the video above, a "salon" or "dining room." It's important to distinguish between British and American English, because in cowboy slang, a saloon is a bar! You'll see "saloon" written on the sign of nearly every bar shown in Old West films.
Who's that old dude? -Oh, that's JJ, our grandpa.

"Dude" is still commonly used used to mean "man," as in the above video. But to call someone a "dude" in cowboy slang is a sort of insulting term for somebody from the city who is not familiar with country life. Luxury hotels that have ranches and include horseback riding among available activities are called "dude ranches."
Watch the video on Yabla English about Annette's visit to the Wild West town of Deadwood. Then see if you can find out the meanings of some other cowboy expressions such as "city slicker," "tenderfoot," "pony up," "in cahoots," and "yonder."
