"Hundreds of ..."
Please note we are not looking for anything necessarily negative or disgusting. The goal is to elicit an unenthusiastic "huh" from someone hearing the completed phrase.
That's a "huh", not an "ew."
The instigating phrase last night was: "Hundreds of ... baggies." Deflating, but is it the deflatingest? Only you can tell us!
