Noun: A internet "link" that does not work to specification. Specifically if video and or sound is inoperable and henceforth ruins the masterpiece that is a short clip of a cat falling off of a table while Alicia Keys plays triumphantly in the background. A noise most accurately described as lunk is generally heard either in the distance over the left shoulder, or in the third eye region of the brain between the eyebrows and 1.5" behind the skull, as the viewer realizes that the link they were sent does not work.
You sent me a lunk! That youtube video of the epic finale of Pitch Perfect 2 had no sound! Send me a link please.
