When it comes to finding and registering new domain names, are there certain words that you typically try to stay away from that are not considered 'illegal' words?

For example, typically i will stay away from using the word 'boy' in a domain name, likewise, ill typically not register a domain that has the words 'abuse', 'extreme', 'obscene' etc in them because i feel that the name could conjur up thoughts to the surfers (and authorities) that the content on the name might be considered borderline illegal.

So, are there words that are not considered 'illegal' that you try to stay away from when it comes to registering new domains for whatever reason?
