I read a sentence in Word by Word by Kory Stamper which was:
Ask any lexicographer who has been at this gig for a while what word had them hunched over their cubicle at 6:00 p.m. on a Friday, hands clutched to their temples, the office copy of Quirk open on their desk while the night janitor loudly scrummed with the big recycling bin, and the answer will not be a polysyllabic hummer like "sesquipedalian."
I am not able to figure out what the word 'scrummed' mean in this context. Most of the dictionaries say that it is mostly used in the context of rugby game meaning 'jostling'. Any help would be appreciated.
