1. The correct McDonalds term for the male reproductive organs, (sausage) being the penis and (mcballsack) being the testicles. The mcbalsack, when placed into the mouth, will consequently eject a sticky syrupy substance commonly equated with mansauce or cum.

2. A slang term for the sausage mcgriddle to further express the digustingness of its taste, texture, and stickyness when place in the mouth.
1. Drive thru orderer: "I'll have two sausage mcballsacks with extra mansauce, please."
Drive thru worker: "Do you mean two sausage mcgriddles with extra syrup?"
Drive thru orderer: "Gimme my mcfood before I chop off your mcballsack."

2. After having that delectable hot sandy from Tyler's mom last night, the sausage mcballsack tasted like the inside of David Hasselhoff's skin tight speedo.
