Yeah, seems like a bug in either their link shortener or their internal routing:

• Clicking the share button on the correct definition gives me http://cherry.urbanup.com/757445 which seems right so far. 757445 is the ID of that specific definition
• When visiting http://cherry.urbanup.com/757445, it gets expanded to https://www.urbandictionary.com/define.php?term=Cherry&defid=757445 which still has the correct ID but for some reason still shows the full list.

To fix this, they should either

• Expand the shortened link to https://www.urbandictionary.com/define.php?term=Cherry&defid=757445#757445 which makes the browser scroll down to the right definition, or…
• Have https://www.urbandictionary.com/define.php?term=Cherry&defid=757445 show a different page with only a single definition and a link to the full list
