This clip is a long straw gurgle, the wet, bubbling noise of someone sucking the last drops from a cup for about sixteen seconds. It feels awkward and funny at once, like a small, noisy embarrassment that keeps going past the point of politeness. The drawn-out slurping makes it easy to picture an empty glass and a person who has not noticed yet.
