I have never seen or heard it used in actual speech or text. But I looked it up online, and it is defined as "Go about with much noise and fuss; gallivant around." Basically, it means moving around and making noise.

"But, as it turned out, Mama got plumb tickled when I called her out to the porch and set the baby mink down and it began to tarryhoot around. “It looks kind of like them pictures of the rich women in the Sears-Roebuck catalog,” Mama allowed. “The little hussy!" - Old Crip You can guess the meaning from the context. We still use "gallivanting around", "gallivanting off" and "out gallivanting". Notice that we almost always use it in the continuous sense in a sentence. I think the word is too wonderful to be replaced with a "modern equivalent". :) There's "gad about", but that's an even older expression.

I watch English movies as well. Last time you didn't recommend me to watch "The Star Wars" http://www.italki.com/question/237161. "The Fox and the Hound" is an old, but very beautiful and kind American cartoon. I don't regret watching it. Haven't you seen it? I couldn't find only the meaning of this one word. For this reason I asked native speakers for help. There are many old-fashionable words in classic works.You don't recommend to read them either, do you?

Cartoon English is not regular English. Well done to Mike for taking the time to look it up. Perhaps you should watch English movies instead.

I think, it's old.The sentence is "You barge in on somebody's house like you own it tarryhootin' around them woods, wakin' up folks in the middle of the night." It is from the cartoon "The fox and the hound".
