COB stands for "close of business," which refers to the end of a business' operating hours for the day. It may be used when talking about the hours that a business is open and can take customers or the time of a deadline.
You will most likely see COB in work-related emails, and possibly in text messages. When used in emails, it is typically utilized by a superior who wants something completed by the end of the workday.
As businesses become more accessible online, COB has become less of a description of in-store business hours, and more of a description of the end of the workday for employees. COB may be interchanged with "EOD."
