( CNN ) -- It 's a trip that would make Demi Moore and Ashton Kutcher blush . On Friday , the Carnival cruise ship Elation , sponsored by the world 's largest nonprofit singles travel group , will make history by hosting the world 's first International Cougar Cruise , and we do n't mean the animal . Defined by the Urban Dictionary , a cougar is `` an older woman who frequents clubs in order to score with a much younger man . '' It can be anyone from `` an overly surgically altered wind tunnel victim , to an absolute sad and bloated old horn-meister . '' `` A cougar is generally known as a woman over 40 who likes to date younger men , but theoretically any woman who dates younger men is a cougar , '' said Rich Gosse , who came up with the cougar cruise idea . The ship , which sets sail from San Diego , California , to Ensenada , Mexico , for three nights , is booked for 300 guests and even has a waiting list . The ship has three swimming pools , a seven-deck-high atrium , bar and grill , a Moroccan-inspired Casablanca Casino and a lounge that features stage shows , according to Ann Thomas , owner of the Singles Travel Company and organizer of the Cougar Cruise . After making port in Ensenada , the cruise offers extracurricular activities like horseback riding , ATVing and other outdoor excursions . `` There 's at least four or five options a day for people to get together on the cruise . We 're doing lots of activities ; dancing , dining , Jacuzzi parties , karaoke for two hours . And starting at $ 125 a ticket , it 's a great price , '' Thomas said . `` I 've had to hire two more people part-time just to pick up the phones , '' she said . `` I 've never seen a response quite like this . '' Thomas admits that she was hesitant to sign on to the idea but is glad she did . `` We have people flying in from Italy and Denmark . My associates have been booking from France , Canada . It 's fascinating , '' Thomas said . Gosse , who has been hosting singles events for more than 30 years , said he got the idea after hosting a cougar convention in Palo Alto , California . `` We had to turn away hundreds of people , '' Gosse said . `` Then we did one in Beverly Hills and had a massive crowd down there , so I thought , maybe we should do a cougar cruise . I did n't think anyone would want to go . Needless to say , the phone is ringing off the hook . '' These cougars may as well be an endangered species compared with those hunting them on this cruise . `` The basic problem is , we have is too many cubs , '' Gosse said . `` We usually have too many women and not enough guys , but there 's been a paradigm shift in recent years , so now the cubs are more excited about it than the cougars . '' A `` cub '' is someone in their 20s or early 30s who likes to date older women , according to Gosse . For years , he says , it 's been socially acceptable for older men to date younger women . But in recent years , a phenomenon sparked by celebrities like Kutcher , baseball player Alex Rodriguez ( who is said to have dated pop star Madonna ) and others has led a new generation of younger men on the prowl for more experienced partners . There is even an ABC sitcom called `` Cougar Town '' that glamorizes the sexual escapades of a 40-something divorcee on a search for self-discovery by dating younger men . `` Tim Robbins [ and ] Susan Sarandon was the first high-profile cougar-cub relationship , '' Gosse said of the actors , who have been together since the late 1980s . `` Now we 're seeing a paradigm shift where these younger guys are actively looking for older women . '' `` If you look at the demographics , the only logical way for people to get their needs met is for younger men to date older women , '' he said . According to the U.S. Census Bureau , for every 100 single women in their 20s in America , there are 118 single men in their 20s . The reason , Gosse said , is that young women are dating older guys . `` When you 're single , you always wish the person meets someone they want to be with . If this is something they want , then I wish them well , '' Thomas said .
