My hammer mantra is a lot simpler than yours.

I throw on the third wind so I say "Boom" on the first wind, "Boom" on the second wind, and "POW!" on the final wind. Got the idea from the Black Eyed Peas.

Thought of getting knuckle tattoos once that said T-A-K-E and T-H-A-T with one side backwards so that when I held the hammer or a baseball bat it would read properly.

The reason I say my mantra out loud is that it reminds me to breathe during the winds.
