Machine translation (MT) systems such as Yahoo's Babel Fish tend to mistranslate テトリス (Tetris) as "Tet lith". In Japanese, テト (Teto) can refer to Tết, the Vietnamese lunar new year holiday, on which the Tet Offensive of the Vietnam War was fought in 1968.
This usage is very rare in Japanese, but popular MT software still has "Tet" in its dictionary and not "Tetris".
"Liss" and "Lith" often appear in names of games originating from Japan, such as: Super Tetris 2 + Bombliss, Super Tetris 3 (including Magicaliss and Sparkliss), and the fan game Emlith.
