Daddy hands
Daddy hands are like having a wrestling coach for your hands. You train your off-hand so hard it can slap a kid’s face and still have energy to grab a donut.
I trained my off-hand so much, I could grab a donut and slap a kid at the same time.
My off-hand is so strong, it could punch a hole in a wall and still hold my phone.
I’ve been doing grip-strength training so long, my off-hand could wrestle a bear and still make me a sandwich.
