The most ridiculous, pointless, and redundant adjective that has ever existed. More specifically, it's what a lot of uncreative and ignorant incorrigibles use in their personals ad when they can't think of something to say that actually has meaning to it. The definition of fun, is something that is a source of enjoyment, amusement, or pleasure. Therefore, the fact that something fun is enjoyable or pleasurable is built-in to the very meaning of the word. Hence, it is completely redundant and illogical to say "fun-loving". How else is someone going to feel about fun? Fun-hating? The very notion is contradictory at best, and ludicrous at worst.
