Don't, it's a trap

what if I want to learn about warhammer 40k?

Well- kissing a man isn’t the ONLY way to learn about it, but it is one way. I know more than a couple women one could kiss to find out about it too, but- asking usually works too. If in doubt you can buy a Juggernaut and toss it at someone that is like 70/30 start a conversation or get kicked out of the store. At least according to my research.
