I'm studying English watching TV shows. This week, I was watching God's Favorite Idiot, Season 1 Episode 4.
In the scene, Clark, the protagonist asks the god what he should do for the god. Then the god answered his question, mentioning "full crazy train". Do you happen to know what does that mean? Here is the context for your reference:
Clark: What exactly is the message I'm supposed to get out there?
God: I need you to let people know that God is real and God is good. And everybody, meaning all religions are actually quite right about God. Also, nobody's really wrong. I'm okay with all flavors, unless you're full crazy train, or use my name to hurt people.
Thanks in advance!
