social host(It's a legal term that refers to anyone who hosts any kind of a social gathering non-professionally. E.g. if you invite some friends to your house, you become a social host. The legal aspect revolving around it is that you may become liable for anything bad that happens at your gathering, such as underage drinking or the people you invite getting into trouble due to being intoxicated from alcohol or drugs that you served.
