Yes, it is common to have a middle name in western culture! It is likely to be asked, "what's your middle name?" by a friend or someone you're getting to know. However, a stranger or acquaintance would not ask you this. Sometimes this name originates from other family members' names to honour them, or it is just because the parents liked this name. Ex: My middle name is 'Heather,' after my grandmother. Ex: Hey, Jerry, what's your middle name?
