This tag signifies that the tagged video is in some way a reference to the video Scary Monsters and Nice Parasprites. This includes videos referencing the "I'm not a YTPMV'er." copypasta, but excludes videos that only call themselves a PonyDub without having other elements indicative of the fad.

Scary Monsters and Nice Parasprites is a PonyDub created by RabiesBunx87 on July 17, 2012. The video's original description reads:

I'm not a YTPMV'er. My goal is towards learning music and eventually making my own content with what I like (in this case ponies). I'm still studying how music works and this is what I can do so far, so to all the ytpmv'ers out there: Please stop following my videos, cause I'm not interested in making chiptune music with your rules you set up on how to make YTPMV's. Also I'd appreciate if you guys would lay off bronies in the comment section, cause these are made for them and not for people who doesn't like ponies.

The description was changed shortly after posting.

The video and its accompanying description spread throughout the YTPMV community, leading people to make response videos. These videos typically have a parody of the "I'm not a YTPMV'er." copypasta in the description and a play on [PonyDub] in the title. Videos will often have the BGM Scary Monsters and Nice Sprites by Skrillex, though this is not always the case.
