B-M 

The condition of every human being that is afraid to admit they had a BOWEL MOVEMENT.

I don't understand why a huge corporation has to take credit for our movement of our SPHINCTERS and the waste matter resulting from it given the fact that we are afraid to attach any possessive speech to our ASSHOLE TOILET EVENTS yielding B-M.

At least attach a friggung name to it and say that is " WATSONS B-M.

OMG that B&M was great! How do I know that was a B&M? By the characteristic roar! Did I mention I'm a rollercoaster enthusiast?
