For those who don't know, "the fifth" means the "5th amendment" from the US Bill of Rights. It is the right to remain silent, protecting a person from self-incrimination.
This is just a joke comic, Clownpiece canonically isn't American.
Also, I'm not from the US, I just happen to know about the fifth from watching a bunch of US crime shows and law firm youtubers.

Btw, I'll leave my shameless plugs here:
