Jill: "Apparently he claims to be a good friend of Matt Shadows of Avenged Sevenfold."

Jack: "What a total bragavond."
An annoying Facebook status update in which an insecure person consistantly boasts or brags about ones life, husband, children, animals, turd size, ect. in order to impress others and convince themselves of their fantasy life because they suck in the real world.
EXAMPLE: "Look at Buffy's status, she's a bragbooking fool! Didn't her momma teach her anything?"
BUFFY: My life is PERFECT, I have the BEST husband in the world and the smartest kids who do no wrong! I love you Mack!!!
One who's repetitious bragging resembles a prehistoric beast's warcry. These folks aren't ones you would wish to spend long amounts of time with. You will spend the majority of your time with them figuring out who to get them to leave.
