a penis that appears small when limp but SUPPOSEDLY gets bigger when erect.

however, this phenomenon does not actually exist and this term was invented by a man who was caught with a limp penis by one of his friends and quickly tried to justify it by saying he is in fact, a grower rather that admitting the embarrassing truth that he is less of a man than his friend with the big dick
Friend 1: You bro i think your dicks hanging out, not even trying to front, you got that small dick...Friend 2: no (nervously covers up) im a grower, it gets way bigger when im hard...Friend 1: so does mine...Friend 2: na like way bigger
