Misleading Thumbnail

Also known as "Fake Thumbnail", a controversial type of thumbnail on YouTube in which a YouTuber would use this type of thumbnail to grab user's attention and then trick them into thinking there is a actual content on the video itself, such as a image edited with photoshop of the content in the video to even exaggerate the result as well.

"I have ever seen a misleading thumbnail featuring my hobbies i love like Apple products and other high-quality products." - The creator of this definition

thumbnailer

term used to describe a person that appears to be attractive in a thumbnail picture on a social networking website, however, the full size image reveals their ugliness.

sometimes used to describe if you would have sex with the person if they did, in fact, look how they do in the thumbnail image.

goes along with the trend of people always placing the image they look best in as their profile picture.

I was browsing Facebook today and ran across what i thought was a cute girl. She looked good in the small picture, but once I clicked on it I found out she was a thumbnailer.

Thumbnail Beauty

A person, usually female, that is only attractive in a thumbnail image. This is similar to HFFA.

Josh is browsing on the Internet when he sees a thumbnail of a girl.
Josh: Oh, she's hot!
Josh clicks on the image
Josh: Shit, she's a thumbnail beauty!
Josh then proceeds to vomit all over the screen, probably in an attempt to shield his eyes from the girl's ugliness.
