Clicking like or dislike on Urban Dictinonary, not based on whether your actually like or dislike the defintion, but rather, to see the little counter flip over to a high and round number: The more zeros at the end, the more satisfied you feel. While the more passive "constant refreshing to watch the milestone pass" is not updown rounding in the strictest sense, it, too, can be addictive.)
