When someone's had a lot of modifications made to their penis, oftentimes it results in sundry effects on the urine stream. A sprinkler-head effect is when the urine comes out like, well, a sprinkler - either one of those flat ones which makes a nice rainbow arc back and forth across the lawn, or a round one which sprays out in all directions.

On a similar note, a female-to-male transsexual may encounter a problem with his new penis: the skin used isn't used to standing up to urea, and it slowly gets dissolved by their own urine. End result? This. (Though in this context it's usually referred to as a shower head, rather than a sprinkler head, probably because it's much more like a shower than a sprinkler.)
