I'll tell you that shit for free
when you’re so proud of your knowledge you don’t even bother to charge for it
You: 'I’ll tell you that shit for free' because you think you’re the smartest person in the room
Your friend: 'You’re like a know-it-all with no money' because you keep giving away secrets
You text your mom: 'I’ll tell you that shit for free' because you’re too confident to even ask for a thank you
