Person who likes to joke around and have fun but sometimes occasionally they look at a person. At least ten times a day if you count. And they hella sus.
"hey he's looking at you again"
"Amenayo.."
"Lol he's boosting ur egotoo much"
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.
