An adjective of enthusiastic approval or glee, usually used as an exclamation. Its Western usage is believed to have been derived from the popular anime Ranma ½, in which diminutive, lecherous, old Happosai faithfully spouts his catchphrase "OH, SWEET-O!!!" at the sight of women's undergarments. The "O" at the end is a consequence of the lack of syllables in the Japanese language that end in consonant sounds, save for the syllable "n".
