Favourite female co-worker who you get along with really well and enjoy spending time with but in a plutonic way. She's your girlfriend between 9 and 5 without sex.
Guy: My work girlfriend said the funniest thing this morning.

Guy's actual girlfriend: WTF? you cheating on me? Why don't you go and tell your "work girlfriend" that you can't even shave your own ass.

Guy's friend: Only dumbasses used the term work girlfriend in front of their actual girlfriends.
