This is Ironic.... Cause I just changed mine

I was JT Rock because I WAS in terrific solid shape.. not so much now(far from fat though) also I earned the name Rock from being hard edged in my approach along with being unbending, unyielding and percieved as lacking compassion for my no nonsense poker face...

JT is my nickname and it comes from my first name JOSEPH middle name THOMAS, hence JT

I just switched to MENACE I earned that nickname years ago through my relentless fighting and bouncing style, also at times I am like a bull in a china shop.. So they would say I was the Menace
