I've been a white guy since the 80's and I have no idea what an IPA is. It is a beer. It is a "pale ale" whatever that is. It also comes equipped with the letter i. Is that all there is to know?
I think you meant to say, Girls are addicted to lattes and Boys are addicted to beer. And if addicted hard enough will make their addiction a part of their personality.
The I stands for India as the British used to have to stick loads of hops in for the ale to make it to India without going off as hops are antimicrobial.
