I don't think the reviewer has a "pansy" nephew to be honest. If you look at the rest of their reviews, they are quite liberal with reality and aiming for humour.
On some Ugg boots: "What I did not realise is how much of a turn-on Camel's feet can be. I now insist that [my girlfriend] wears them all the time, even in the bath. I also got a suede beige cushion that works perfectly as a hump and sets the Uggs off a treat! My Camel obsession has now spread to Llamas and all kinds of spitting, four-legged creatures."
On a Rabbit vibrator: "This book unfortunately has nothing to do with Rabbits. Hardly Watership down. Disappointed and confused. Also allergic to rubber. I would recommend Peter Rabbit in Paperback version, especially for younger kids. My 4 year old will never be the same again after Ive finished reading him this one."
I think they are just trying to wind people up a little bit with a spoof post.
