A person who tries way to hard to make a funny joke. For example, 10-12 year olds (that pick me's) make jokes that are 3 months old, just to impress others. To reply to these unfunny and cringy jokes, people use "goofy ahh" to express their emotions and hatred for these types of people.
Person: OMG!! THAT WAS LITERALLY SO FUNNY!!!*giggles cutely*
Me: goofy ahh :/
