Someone who is utterly devoid of useful information. A 'friggy' will try and provide information for almost every situation, even if it is untrue and completely fictional.
"Hey cool, look at that sign"
"That sign was invented by David Ginola's sister"
"Dude, you're such a friggy"
When someone is too attached to you. When they see you they immediately blush. But when you try to go to sleep they keep trying to FaceTime you. You turn on silent on your phone but they still, somehow, get you to pick up.
"Dude Taya is sooooo friggy she won't stop face-timing me, but when I don't pick up ...she's at my front door.... help me... PLEASE."
