Vietcong is a first-person shooter set during the Vietnam War, first released in 2003 by Czech developer Pterodon, and its soldiers speak in terse, battlefield-ready lines that suit the game's tense jungle missions. Já čekám, a Czech phrase meaning I am waiting, has survived beyond the game because short foreign-language voice lines travel well in short-form video, where viewers do not need a translation to feel the impatience. Gamers reuse it as an in-joke for waiting, and its five-second length makes it easy to share in memes, edits, and soundboards.
