Yeah, there is no word that fully describes the combination of "I want to protect her!" and "At full force in the vagina, mouth, and anus" feelings that moe comprises.
Likewise, "self-published comics" is too long, so I say "doujinshi". "Fanzine" is in the general ballpark, but doesn't really mean the same thing.
But people who use Japanese words in English conversation when there are perfect English equivalents (like baka, neko, suki, etc) it seriously pisses me off.
