The Grinch in an Ice Storm?

OK, so I was wasting time on IMDB, and happened upon Ice Storm. It says that the movie was spoofed in 2000’s How the Grinch Stole Christmas. I’ve seen both movies and don’t see the connection. Could someone explain it for me?

The key party?

Ah, that’s it. Thank you! I’d forgotten that bit entirely. I had thought they were referring to the entire movie being a spoof!
