The 'Oh really?' sound, often delivered with a sarcastic or incredulous tone, is a popular reaction meme originating from various sources, notably the character Randy Marsh from South Park. This sound is perfect for moments of feigned surprise, skepticism, or to call out an obvious statement or an unconvincing excuse. Its cultural context is rooted in the dry, often cynical humor prevalent in internet communities, making it an excellent tool for comedic commentary. It serves as an auditory eye-roll, conveying a sense of 'tell me something I don't know' or 'I'm not buying it.' This sound shares a similar function to the Bruh sound in expressing disbelief, but with a more pointed, questioning edge, often seen alongside the playful irony of a meme sound, or the more direct challenge of Нет иди нахуй.
