The act of zoning out, mindlessly staring into space, or losing oneself in thought; often done humorously or casually among teens. Not necessarily associated with anything inappropriate or explicit.
Spacing out, staring at nothing, or just totally zoning. Usually when you’re bored, tired, or your brain just decides to take a mini vacation. Nothing gross or weird, just funny or random.
"I totally missed what she said, I was gooning the whole time."
