Grand master stands for great mover... prove me wrong (i do know but i thought this was funny)

You're wrong. GM is Garbage Master. As the famous saying goes:

"Either you're not a master (NM), or you're a fake master (FM), or you're an imposter (IM), or you got the title by cheating (CM), or you got the title but it's garbage (GM)."- Joseph Truelson

False 

cm is cowardly master

I am a SM. 

a super mover?

The clue is in my username Columbo.

I'm a BM, blunder master

I must be Columbo because it was pretty obvious to me that their SM is "strange mover"

Also, "one more thing sir..."
