A Banter Biscuit is the official tea dipping material that is often rewarded from a banter overlord to his squad when one or more members incite "witty banter" into a chat.

This witty banter can be applied through the use of both text, speech and through images often combined to create "memes".
Person 1: "That was some great, witty banter there."
Person 2: "Cheers butt."
Person 1: "I award thee a banter biscuit."
