When meeting a person online or in a video game posing as a female to get money or items, and later turns out to be a man.
John: Man, I met this girl on WoW the other night. We sexted for hours.
Rick: You mean Superhotty6969? Yeah, pretty sure that's a dude.
John: No way, I think my junk would know if it was a dude.
Rick: Sounds like erection deception to me.
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.
