The worst implementation of a SHARE feature.
It can be found under every single definition for the word BUT it only shares the top definition!!
Obviously if there are multiple definitions in a close race for the top spot you may like one of the other definitions but no matter which SHARE THIS link you click it shares the 'winning' definition.
UrbanDictionary's SHARE THIS option is the Epic Fail of Social Networking
Sharing known to mankind!
