A type of icy snow

While playing Minecraft with dad:

Lars: What the hell!
Mom: What did you say?
Lars (sheepishly): “What the hell”
Mom (sternly): Oh, we don’t say that…
Dad: Do you know what “hell” means?
Lars (matter of factly): A type of icy snow
Mom: Well, that’s *is* grammy’s version of hell.
