The "Lie meme" sound is typically a short, often dramatic or exaggerated vocalization that signifies a falsehood, disbelief, or a moment of being caught in a lie. It can range from a drawn-out "Liiieee!" to a more subtle, disbelieving gasp. Its humor often comes from its application to trivial situations, creating an ironic overreaction. This sound is a direct auditory cue for deception or disbelief, much like the sudden realization in a brain fart meme, and can be used to highlight moments of comedic untruth, similar to the dramatic irony of an italian brainrot ringtone.
