Sivir has been part of League of Legends since its early roster, as a Shuriman mercenary captain famous for her large crossblade weapon and treasure hunting work. Her short voice calls were built for fast team fights, where a warning has to be understood instantly. As League clips moved onto soundboards and short video edits, brief champion calls like this heads up line became easy reaction sounds, reused by players who recognise the champion from a single second of audio.
