To hightail is to leave or move very quickly. Your plan might be to hightail to New York City as soon as you graduate from high school.
Hightail is a useful, informal verb that means "get out fast" or "make a beeline for" or "cut and run." Bank robbers might jump in their getaway car and hightail it to their hideout, and a shivering snowshoer might hightail it to a cabin with a warm fireplace after hours out in the snow. Hightail is 1890s U.S. cattle ranch slang, from the way a running cow or bull raises its tail.
