otoko 男, 漢

In Japanese, otoko 男 means a "man," and otoko 漢 means a "MAN." A man among men. Whose pride, bravery, and dignity is unrivaled.

This, of course, isn't an actual word. It's a meme. It shows up in manga and anime from time to time.

Normally, "man" in Japanese is spelled otoko 男, as seen in words like otoko no ko 男の子, "male child," "boy."

The manga slang otoko 漢 is an ateji, that is, we're spelling with a certain kanji a word that doesn't have kanji or is normally spelled with different kanji. In this case, 漢 is the kanji for "man" in Chinese. Normally, it can only be read as kan 漢 in Japanese, like in chikan 痴漢, "foolish man," "molester." (another manga ateji is otokonoko 男の娘, "trap.")
