What does grower versus shower mean?

Showers are those who have a penis that does not fluctuate considerably in size between flaccid and erect states. A grower, on the other hand, is someone whose penis size fluctuates dramatically between flaccid and erect states. When the penis is flaccid, people can measure it from the base to the tip. When their penis is erect, they can take the same measurement. People are considered growers if the discrepancy between the two measures is larger than 4 cm. People, on the other hand, satisfy the definition of a shower if the difference is less than 4 cm.
