A raw socket is a socket that takes packets, bypasses the
normal TCP/IP processing, and sends them to the application
that wants them.

Raw mode is basically there to allow you to bypass some of
the way that your computer handles TCP/IP. Rather than going
through the normal layers of encapsulation/decapsulation
that the TCP/IP stack on the kernel does, you just pass the
packet to the application that needs it. No TCP/IP
processing -- so it's not a processed packet, it's a raw
packet. The application that's using the packet is now
responsible for stripping off the headers, analyzing the
packet, all the stuff that the TCP/IP stack in the kernel
normally does for you.
