To barhop is to visit several bars in one night, have a drink, then move on to the next. You do not settle in one place. Friends do this together. It is informal, and it feels especially American. British speakers understand it, but they more often say they are on a pub crawl. The mood can sound light and social — though actually, because each stop is “just one more,” people sometimes drink more than they meant to. You would not use barhop for a quiet evening in a single bar, and you would not write it in a formal letter. A person who does this is sometimes called a barhopper; the verb is the word you will meet first.
