It's not a bap, it's not a roll and it's certainly not a barm cake here in Nottingham. That small round of bread surrounding your ham, egg or cheese is a most definitely a cob. According to Collins English Dictionary a cob is also a strong horse with short legs, a male swan, something that sweetcorn grows on and is also slang for a mixture of clay and straw used for building material.

Nikkita Marsden, who has run the Cob Shop in Derby Road since last July, confessed: "I don't know. Genuinely I have no idea . Is that bad? I own a cob shop and don't know why it's called a cob." In a reference to the phrase 'get a cob on' - meaning to get annoyed - she joked: "Is it because you get a cob on if I throw it at you?"
