“Caped on the net” means someone is lying or exaggerating online, often trying to make themselves look better or seem more important than they actually are. It’s similar to “capping” but specifically refers to online behavior.
1. “Dude said he owns three Lambos, but we all know he caped on the net.”
2. “She be caped on the net talking about she met Drake, but ain’t got no proof.”
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.
