Top definition
The noise you hear on the other end of the phone when someone's cell phone key pad got mashed in their pocket and accidentally called you. The person who called doesn't even know they've called.
The sound is usually a combination of static, muffled voices, loud bar music, or inaudible random conversation.
This often leads to incredibly long phone messages, and potentially large long-distance charges.
"Dude! You called me earlier today, but all I heard was pocket noise."
