A very small penis, good for learning with but
useless after that. Generally small in length and girth so it is less painful for virgins, but once they get used to having
sex it is of an insufficient size. The term is derived from skiing and snowboarding where the starter hill for beginners, or bunny hill, is shorter and less steep and therefore easier for those beginners to cope with. Although the bunny hill is generally regarded as boring for those who know how to ski or snowboard, or in this
case have
sex. Often anything less than five inches
long (12cm) and 4 and half inches in girth (11cm), but is definitely relative to the dimensions of the other sexual partner.
