Due to the way the algorithm works, the thesaurus gives you mostly related slang words, rather than exact synonyms. The higher the terms are in the list, the more likely that they're relevant to the word or phrase that you searched for. The search algorithm handles phrases and strings of words quite well, so for example if you want words that are related to lol and rofl you can type in lol rofl and it should give you a pile of related slang terms. Or you might try boyfriend or girlfriend to get words that can mean either one of these (e.g. bae). Please also note that due to the nature of the internet (and especially UD), there will often be many terrible and offensive terms in the results. Special thanks to the contributors of the open-source code that was used in this project: @krisk, @HubSpot, and @mongodb. There is still lots of work to be done to get this slang thesaurus to give consistently good results, but I think it's at the stage where it could be useful to people, which is why I released it.
