I don't know; or in other words: I do not give a fuck about what you're asking me.

Mostly used when you don't want to start a conversation with someone.
1. Mom: "What do you want to eat for dinner, son?"
Son: "I don't know, mom."

2. Joe: "How are you doing that?"
Billy: "Dude, I don't know."

**Real Signification**:
1. Mom: "What do you want to eat for dinner, son?"
Son: "Shut up, mom, I'm doing something more interesting than you."

2. Joe: "How are you doing that?"
Billy: "Dude, I don't give a damn about you. Get the fuck out."
