|1.||five related words|
Some dumb bullshit the Urban Dictionary developers thought up to try boosting their tags system. Even though the tags system holds no relevance in the site, and some words have no 5 related words (like p), you still have to bullshit up 5 related words.
Right up there with "Location", which nobody in their right mind would ever honestly fill out.
Tags should be at least five related words, separated by commas.
