The Liam Dayquan in ur ass clip circulates as a user shared soundboard meme with no confirmed source work, performer recording or original release attached to it. Its spread comes from that anonymous, inside joke quality, where the specific name makes it feel like a callout even to listeners who do not know anyone involved. Short voice memes like this are passed around in gaming and chat communities, reused as instant roasts, and kept alive because the phrase is memorable, quotable and easy to drop into unrelated situations.
