My Pet Peeve: People who dont understand that "Electoral College" refers to a specific group of people (the electorates) and NOT to the system of voting that governs them.

For example when we talk of the presidential election in america the "Electoral College" does not describe the fact that each state has a set number of votes or the fact that the popular vote may differ from the actual vote. It is instead a term used to refer to refer to the 538 electorates in the USA, people who cast votes for president.
