Slurp sounds like this one have become a staple of short-form comedy because the noise itself is instantly readable without any dialogue. Clips labelled slurfff circulate on user soundboards where creators grab quick effects for edits, streams and group chats. The drawn-out spelling mirrors the drawn-out sip, making it easy to find when someone needs that specific straw-emptying moment. Its popularity comes from timing rather than a single source, and it keeps resurfacing in food videos, anime edits and reaction memes where an obnoxiously loud drink breaks the tension.
