At 1:35 into this clip of the animation movie 'Despicable Me 3', Dru shows his twin brother, Gru, their dad's supercar:
Dru: Dad's villain wheels. Pretty slick, huh?
According to this previous question about the difference between slick and sleek, John Lawler says in a comment:
Slick is a pejorative term, but sleek need not be.
And the only answer having 9 votes says:
To me, slick is more about touch: slippery, and sleek is more about sight/appearance. A wet moss-covered surface is slick. A satin skirt is sleek.
To which John Lawler agrees.
As far as I know, Dru wasn't portraying his dad's car in a negative way at all. Also, it's all about "sight/appearance" and not really about "touch".
Then, why is slick used instead of sleek here?
