Rammus is an armadillo champion in League of Legends, released by Riot Games in 2009, and he became famous for a vocabulary limited almost entirely to ok, yeah and similar grunts. In the French localisation that minimal line becomes ouaip, the casual spoken form of oui. French speaking players clipped the short reply and shared it outside matches as a standalone reaction, where its brevity works even for listeners who do not play the game. It remains popular because it captures Rammus's whole personality in one indifferent sound.
About this sound
The French ouaip is Rammus's short League of Legends voice line for yeah, used as a deadpan yes and a quick agreeable reaction in game clips and chats.
This is the French voice line for Rammus from League of Legends, reduced to a single flat ouaip that lasts under two seconds. His voice is deep, slow and completely unbothered, delivered like a shrug rather than an enthusiastic yes. Because Rammus is famous for saying almost nothing, the deadpan agreement feels funnier than a normal affirmation. Played over gameplay or a chat moment, it turns a simple yes into a joke about reluctance, indifference or quiet acceptance, and viewers instantly read it as the character calmly rolling along with whatever just happened.
