A Logan Moment is when the "genius" in your group named Logan, makes a stupid, or downright dumb suggestion, usually involving some form of activity, usually grueling and not worth the time put into it.
Logan Moment -"Hey, lets go play Star Citizen guys, it is a really fun game when you get past the 4 hours of prison time you gotta serve if you get caught"
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.
