A new term coined in 2022 somewhere on Twitch. It is essentially a family-friendly term for coochie.
I haven't been on the stream for 2 minutes and you are already talking about your goontie
Girl, all you do is talk about your goontie
Who wants goontie?
GoonTard - a Portmanteau of Gooner and Retarded. Used to refer to a Chronic Compulsive Masturbator who jerks off for hours and hours and hours every day. He eventually becomes a stupid gooner and looks like he's retarded because his brain has shut down all but core functions. Most guys consider them Idiots and Morons because they have no goals or ambition other than to masturbate all day long, usually on the internet where anyone can see them.
Tim: Hey Ryan, I heard your older brother is a GoonTard
Ryan: Yeah, he's a Total GoonTard.
Tim: Does he really do nothing but masturbate all day?
Ryan: Yeah, mom and dad have given up on him. He hasn't left his sroom in 3 months, so they just slide a plate of food in there once a day.
Tim: Sorry bro.
Ryan: Yeah Me too. I'm afraid I'm gonna become a GoonTard too.
