Liking a YouTube video so much that within the first roughly ten seconds of watching it, you instantly favourite the video.

You (Thinking in head): "I love this video! (Just started watching)"
You (Commenting on video): "Great video! 5/5, instafav. :)"

instafake model

A moderately attractive female who whores herself on Instagram for free, rather than professionally like a super model. Their profile will consist almost entirely of selfies and the occasional "seemingly" candid shot.

"For real tho she looks way better on IG"
"well yeah, all instafake models do."

A powerful fart, immediately filling the room with a terrible smell.

We were riding in the car and my wife let out an Instafart making it hard to keep my eyes from watering.
