Quite a few terms come to mind, but precious few of them suited for polite company. After all, people being what they are, the first thing they'll try to find ambiguity in is innuendo. Sadly, if one trawls the internet, one finds many such terms.
*OOC Note: The rest of this is OOC. Robotnik isn't exactly from Earth, so it's a bit tricky to answer this with these websites, but I want to share it anyway, simply for amusement value
A few website-names come to mind.
There was agentsexchange. A site containing information about whose agent to contact if you needed to speak to a particular person. Another one was a store specialising in high quality pens: penisland. And of course, one of the more famous examples, apparently there was a power company over in Italy which for a short time had the domainname "powergenitalia"
Well done them. Twits.
