When someone you meet on a dating app says they are fit and active and shows you skinny pics. When you meet them they turn out to be fat (cat fished).
If you date them anyway and they make your life a living hell and 6 months later you look in the mirror and realized they made you fat too, then my friend, you have just been "Fish Fried"
A more hardcore version of fried fish, deep fried fish includes a man tucking his balls between his legs. The woman proceeds to lick his balls, and the man shits on her face. The woman may also vomit on his ass.
