profligate

profligate - adj - shamelessly immoral; dissipated; dissolute; recklessly wasteful

There was an article on the news yesterday about the famous polygamist in Utah (currently in prison) who asserts polygamy is a religious issue and is therefore protected under the constitution. If I understood correctly, the suit against him isn't so much related to the issue of polygamy as it is about the underage girls to whom he is either married or has arranged marriages for.
