I crap you negative - When you're not just lying, you're lying so hard you're gonn

When you're not just lying, you're lying so hard you're gonna need a toilet to back it up.

I crap you negative, I wouldn't lie to you about something this big.

I crap you negative, I’ve been through worse than this.

I crap you negative, and if I'm wrong, I'll eat a whole bowl of spaghetti.
