This is what old school dads used to call goofy bastards. People who say or do dumb shit all the time and anyone who has met them just knows they are a gophy bastard. The gophy comes from the east coast connotation because they talk funny...making them gophy know it all bastards toh! It's interchangeable with gophy betch.
Terry do you realize what a gophy bastard you are? Nobody laughs at your lame attempts at humor. Dat Terry......he a gophy bastard. And dat Jane.....she a gophy betch....she so dizzy!
