Slut
From RationalWiki
| A baker's dozen on Human Sexuality |
A slut is someone who likes sex and has a lot of it with quite a few different people. As stigmatized as it often is, it's all good fun for everyone involved as long as the slut in question doesn't needlessly break hearts or knowingly spread disease.
However, some believe that a slut is only a prostitute too dumb to get paid for it. These people sort of miss the point and really need to get laid more; if they keep their opinions to themselves, they might actually find a slut to help them with that.
