Put your bits in a concrete mix

I had to kill him, I had no help
I put him in jars upon the shelf
I chopped you up in little bits
Put you in a concrete mix
I licked my lips as I began to flick
The bloody chunks - I feel so sick
They made a plop as the began to sink
I put your bits in a concrete mix

A freshly dug hole,
Filled with 'crete
Soon to be scattered with human meat
Large squares and tiny chunks
Hitting the liquid -
Instantly sunk

Concrete, I put your bits in a concrete mix
