She often talks about womens clothing have inadequate, no, or fake pockets. I do like pockets myself and I love my winter jacket which has a ton. As I have gotten older I have gravitated to more comfortable and usually lighter clothes which usually have fewer pockets (although being mens clothing it still has them). I liked how woman have purses to carry stuff but am not wild about them. I used to sport a fanny back but now I have a homemade sorta bandolier I use which I find easier to throw on and off and stays more balanced.
Well, I just mean that she is probably using the British meaning of Fanny for the joke... I've never heard of this comic before so I figured it was a one-off.
honestly I thought butt however being fen and likely some degree of anglophile you might be right.
