The stairs to the biggest smite

A: Hey you.
B: Oh, you caught us.
A: Get back in there. No escaping.
B: I don’t like it here. It’s where they keep Riley’s darkest fears.
C: It’s broccoli. The stairs to the biggest smite.
B: Grandma’s vacuum cleaner. Aw!

Question: I looked up the word “smite” in several dictionaries, but couldn’t find the meaning of it as a noun. Is “smite” a verb only?

Thank you!!!

Smite can be used as a noun the meaning is basically the same as the verb. " a heavy blow or stroke with a weapon or the hand ". This is a very strange dialogue. I think this might just be a poor translation. I would just ignore it.
