jailbait pretty much means hot ~14-17 year old, so I don't mean it in a pedo way. In my minimal experience with the body building forums, it seems to be far more prevalent in their culture than in the culture we have here. Searching for jailbait in the forum here: http://forum.bodybuilding.com gives 84 threads (many of which have several dozen posts or more), with titles such as "We need a jailbait thread!!!!!" and "im trying to come up with ways to get jailbait " and "I never had a girlfiend untill I was 18, I missed out on all the jailbait" for some examples. Searching for jailbait here turns up a total of 18 posts containing the keyword jailbait , although that is not the number of threads with a title containing the word. A quick scan through the threads here shows that most of the people saying it are saying it for entirely different reasons than the people on the body building fourms. Then again that forum is way bigger than ours so it makes sense that the number of such threads would scale upwards as well. I just have some association between body building forums and people talking about jailbait, much like the person I quoted associates them with people having avatars of themselves without shirts on, calling each other bro and having absolutely no idea what they are talking about .
