What it means
A brief, often weird malfunction: the screen flickers, the character clips through a wall, the app freezes for a second then rights itself. Beyond tech it covers any little hiccup in a system, a glitch in the schedule, a glitch in the matrix when reality feels off.
Usage examples
"The payment went through twice, must have been a glitch."
"He walked into the same stranger twice in a minute, total glitch in the matrix."
Where it comes from
From glitch, likely via Yiddish glitsh, a slip or slippery spot. Engineers used it for a sudden fault, and gaming spread it to every odd little bug.
