I'll be the first to admit that I am terrible at closing Chrome tabs on my phone, constantly filling them with things that I can't get to at the moment, but also don't deserve a new bookmark. Because of my poor tab management, I'm regularly greeted by a smiling emoticon in place of any indicator of my current number of open tabs. Thankfully, Chrome for Android appears to be testing a new feature, by way of a new flag, that will periodically suggest users clean out their old, unused tabs.
