In mainly Asian countries, the practice is to assign each new Rotarian a humorous nickname relating to a personal characteristic or a descriptor of the member's business or profession .A member nicknamed "Oxygen” is the manufacturer of chemical gas products. "Trees" is the nickname for the Rotarian in the lumber business, "Building" is the contractor, "Paper" is the office supply retailer. Other members might carry nicknames like "Muscles," "Foghorn" or "Smiles" as commentaries on their physical features.
