I know you want to seem like the unaffected cool lib but when you post like this it makes you look like a bimbo.
"Opacity" is a term not often used, commonly more associated with television screens or the like (ex. Gamers often see the word in relation to a sliding scale for text legibility or clearing some part of the HUD to see better, people who watch TV and are changing settings might see it, etc.).
The term more used in common vernacular, both literally and metaphorically, is actually "opaque" which essentially means the same thing ("exhibiting opacity").
For someone not used to the word they would normally recall the association with vision or something to do with making your TV more visible without realizing that they make it more visible with less opacity, not more, hence it's not opacity that makes you see but its absence.
It's an easy mistake to make which we all know most of us would make it, including you, since we're not reading or working with things that usually utilize that term this way.
TL; DR You're a moron grasping at straws and should have just left the quotes as-is because Rudy making a wild guess like a dumbbell is funny--not that he guessed wrong but that he set himself up like a baseball on a tee.
