A long, elastic strand of mucus that dangles from a sick child's nostril when the child cries. This slimy yo-yo often gets sucked up into the nose when the child inhales between shrieks, only to reappear when the wailing continues. Since it's entertaining for adults to watch this, the child assumes your expression of delight is in response to their distress, which only increases the volume and intensity of the tantrum. It's a viscious (and viscous) cycle which might end on a clock-tower with a high-powered rifle.
a nopeopera is any situation in real-life that has less substance or importance than a soap opera but still contains the same amount of drama and bad acting.
That meeting today was the same old nopeopera. Nothing ever gets resolved and we still circle through the same issues over and over!
