You're calling someone out because they said something stupid and you know they're full of crap
You: I know you lying. You said you'd stop eating pizza for a month. It's been two days and you're already at the pizzeria.
You: I know you lying. You said you'd never cheat on your mom. Now you're texting her ex.
You: I know you lying. You said you'd stop screaming in the shower. I heard you screaming in the shower at 3 AM.
