BID? BID!
I don’t think this will come off as funny as my attending tells it in person, but she once had a medical student who thought that the abbreviations “BID” and “TID” were just doctor speak for “I agree” or “Yes, that’s all.” (BID actually stands for “twice a day” and TID stands for “three times a day.” As in, take this pill, three times a day.)
My attending found this out the hard way; she’d always ask the medical student about a patient’s medication doses. The medical student would say “The patient is on Haldol 5mg.” And my attending would ask, “BID?” And immediately the student would nod back with a smile, “BID!”
