NOTE: In 1945 a British 'A' Class submarine, HMS Aurochs, was launched. The submarine's motto was 'Excreta Tauri Sapientam Fulgeat' which translates as 'a bull's excrement can fool a wise man' or Bullshit Baffles Brains. From this we know that the acronym must have been in widespread use during and before the Second World War.
Yeah that's our Malcolm hoping that BBB.
1) A woman who is exceptionally large or chubby that is easy on the eyes or has a huge heart - or most likely both
2) A chubby woman who has exceptionally large assets(ass and a set)
3) All of the above
Offshoot of BBW - but does more justice to the big woman who has a lot to offer
2) "Shes more than just Big and Beautiful to me - shes fucking hot! So she must be a BBB!"
3) "She's got all the assets of a Big and Beautiful Woman - but did you see that cute face and sparkling smile - must be a triple B".
