Naffie
A naffy is a loud, funny guy who’ll help you out even if you don’t ask. But if you mess with his ego, he’ll laugh at you until you’re blue in the face.
'He showed up at my house to help me move, even though I didn’t ask.'
'He laughed so hard at my joke that he fell over.'
'He told me I was a dork, but he helped me with my math.'
