a really funky game that was on our second ever computer which ran on dos... you had to navigate a little blob into the dangerous area to take more safe space but doing a whole rectanle (or other shape) whilst avoiding the bouncy blobs which kill you, or touching your line before it's sealed into a safe space cos that kills you too. as you go up levels there are more bouncy blobs which move faster...
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
