You will really belong in the penalty box in this child's hockey player killer costume. The red and gray jersey with skull emblem tells us what team you were on before you went all psycho, and the hockey stick has (fake) razor-sharp blades at the end to help you with this new hobby of yours (and judging by the blood-covered hockey mask, you've really been throwing yourself into it.) Add some fake blood to other parts of the outfit to be an even bigger overachiever.
