the.com/coffee break

means A short pause from work, typically taken to drink coffee (or do anything else that isn't working), that became a normal, even sanctioned, part of the day.

from A 20th-century American coinage, popularized through workplace and advertising usage — notably a mid-1900s coffee-industry ad campaign that promoted the phrase to encourage office coffee drinking. It simply compounds 'coffee' with 'break' (a pause from labor), but its spread owes a lot to marketing rather than organic slang.
