见封滚
(jiàn fēng gǔn)
This is also another popular internet slang. This phrase is most commonly found on video sharing sites, such as bilibili, where the thumbnails of videos, often depicting a popular anime character, will bait many curious fans to click. In a way, this is similar to the phenomenon that we see in Singapore where instead of bilibili, we have youtube. Many of these youtubers (creators of the videos) would make sure that their thumbnails are captivating. Sometimes, it even has what we call 'click-baits', where they bait people to click on their video.
The original and full sentence is actually: "看见封面我就滚进来" (kàn jiàn fēng miàn wǒ jiù gǔn jìn lái)
