Pin is a pushpin character from Battle for Dream Island, the animated web series by Jacknjellify that began on YouTube in 2010. The character has remained a regular across later seasons Battle for BFB and The Power of Two, which helped short clips of her voice spread among fans. Her exaggerated evil laugh became a reusable reaction sound beyond the show, shared in edits and on soundboards as a quick way to signal a jokingly villainous moment without needing any context from the episode itself.
