If you’ve ever heard people chatting about “jollies” or “rags” at the bookies, you might wonder what they’re talking about. It can feel confusing at first, especially with so many betting terms floating around.
Knowing the right words can help you feel more confident when looking at odds, whether that’s at your local betting shop or on an online site. Many of these phrases go back decades, so once you learn a few, the whole picture may become clearer.
This guide explains the key terms in plain English and in line with UK rules. Read on to learn more.
When people talk about “jollies”, they mean the favourite in a race. A jolly is the runner with the shortest odds, so the market expects it to have the best chance based on form, weight, trainer, jockey and other data priced in by the bookmaker.
“Rags” are the outsiders. If a horse is described as a rag, it usually has much longer odds and is not expected to be in front based on the information available.
You may see these terms most in horse racing. A jolly might be priced at 2/1 or lower, while a rag could be 50/1 or higher. Odds are set using market information and trading models, and they can move as money comes in or new information emerges.
Different sites can present odds in slightly different formats. If you are using an online platform, the help section usually explains how prices are shown and what the key labels mean. The format is not identical everywhere, so it might be worth a quick look.
If you do decide to try your hand betting on horse racing, remember to do so responsibly and within your means; never wager more than you can afford to lose.
Bookies use “jollies” and “rags” as quick shorthand for favourites and outsiders. It keeps conversations brief when there are lots of runners and helps regulars and staff talk clearly about what the market is suggesting.
The language also carries a bit of racing tradition. Saying “the jolly” instead of “the favourite” is common on-course and in shops, and you will hear it online too. It is just a faster way to point out which horses have shorter prices and which sit at the bigger end.
You might hear the terms in other sports, but they are most at home in racing. If a site uses its own wording for favourites and outsiders, the glossary or help centre will usually spell out exactly what they mean.
In racing chat, the favourite can be called the “jolly”, but you might also hear “market leader”. For the other end of the book, “rag” is common, and people sometimes say “outsider”, “long shot” or even “no-hoper” for runners with much bigger odds.
You will also come across “odds-on shots”, which are priced below even money, such as 4/5. A “rank outsider” is one of the biggest prices in the field, sometimes 100/1 or more.
Terminology can vary a little by course, shop or site. Most operators offer a short guide to their terms if anything looks unfamiliar. Picking up these phrases could make reading a racecard and comparing prices much easier.
Favourites are priced short because the available information points their way, but no result is guaranteed. A jolly may look strong on form, the going might suit, and past performances can boost confidence, yet racing still depends on how things unfold in real time, from pace and positioning to split-second decisions.
Rags sit at longer odds because the data suggests they are less likely to be in front. Even so, surprises happen. British racing has plenty of examples of horses at 33/1 or bigger winning when circumstances fell right on the day.
Across UK flat racing, favourites tend to win roughly 30 to 35% of races, depending on the year and race type. That means most favourites do not finish first. Operators set out the relevant probabilities in their rules and game information, so it is clear that outcomes are never certain.
