Today's BWOTD is a term you often hear people use in relation to work and theirs or a colleagues position!
"Oh I'm just the general dogsbody around here"
'Dogsbody' = a lowly servant or the person that does all the yukky jobs nobody else wants to do.
It's not uncommon to hear someone say that they are treated like a dogsbody or know someone who is, it's just a common term in England. So if you're fed up at work and have a good relationship with your boss, you might want to try accusing him/her of treating you like their dogsbody!
If ever anyone asks me to do something I know they don't want to do and it's not a boss, then I will just say to them "Oy what d'ya think I am, your dogsbody?"
