lol: "Japanese slang エッチ (H, etchi, often spelled ecchi by non-Japanese)". Bull.
エッチ IS "ecchi". E + C + CHI.
Yeah ッ is a small ツ(tsu), but here the kana that is extended is チ(chi).
My Japanese romanizer program (Kakasi) agrees.
My JDIC_R (Japanese-English Dictionary System) agrees. Plus, no entry for "etchi" in JDIC_R.
My Windows input system agrees. To input "etchi" gives エｔチ, which is wrong.
