I’m no fan of Lewis Black, but he said it best at least 25 years ago:
“Halftime show at the Super Bowl has gotten exponentially worse, every year in my lifetime. Exponentially means crappier and crappier and crappier!”

"Exponentially" means this year's show is twice (or more) as crappy as last year's show.

Linear growth: f(x) = mx

Geometric growth: f(x) = x^m

Exponential growth: f(x) = m^x

Where "m" is a constant.

Halftime is when the food comes out and people eat.
