Place it at the end of a short edit, right after the win is shown, then follow it with a cheer to stretch the celebration. If the boast backfires, cut to Emotional Damage instead, and use Bruh for a deadpan reply when the win turns out to be nothing.
About this sound
This is a roughly ten-second Rene Puente voice clip centred on the playful line 'toi de campeon,' spoken with a confident, tongue-in-cheek swagger. It feels funny and overblown, turning a small success into a championship moment, and the punchy voice stays recognisable even when heard on its own.
