Benjamin Netanyahu is called "Bibi" as a nickname that originates from a common Hebrew tradition of affectionate diminutives. The nickname "Bibi" is a cute and familiar form of his given name Benjamin. It is derived by combining the Hebrew word "ben" meaning "son" with the first letter of his name, creating a family-centric and endearing name. This nickname, given to him within his family, eventually gained wider recognition and became a popular way to refer to him publicly. Netanyahu himself embraced the nickname, cementing its use both in Israel and internationally. The practice of forming affectionate nicknames like "Bibi" is common in Hebrew culture and serves as a warm and personal form of address.
