grabbing a fish and violently fisting it through the mouth until your hand pokes out the end. From there you use it as a sex toy. From there you drink the cum out of it and say "mmm tastes fishy".

fish fist is when your hands are so dirty if you beat off without washing first, after when your partner goes to blow you & thinks you have been cheating!

if he isn't cheating then he should get new soap to help cure his fish fist. I have a coupon for lotion!
