When you tear ass or fart into someones mouth while they are sleeping. A full glecto is when you press your ass against their open mouth, and fart into it. A full stealth glecto is when you press your ass against their open mouth, fart into it, and they don't wake up.
Dude your breath smells like you got a glecto last night. Hey phil, russ passed out early... lets give him a glecto!
