Top definition
A person that is annoying, arrogant, condescending, lonely, angry, and generally bad to know. A Morendo may also be a "troll".

Originally derived from the musical term morendo (meaning to fade away), this word gained it's urban definition from internet forums (not /b/).
The Morendo madly broke the VCR and continued to mock others on the internet in order to satisfy his/her self pity.
