Is anybody else just sick to death of the term "emergency fund"? If you go to /r/personalfinance, every other comment is reminding people to stock up their emergency fund. Towelie says, "Don't forget to bring a towel!"
I'll tell you about my real "emergency fund": In an actual, living emergency, every single dollar I have, in every account, even my IRA, and all my credit lines combined, are my emergency fund. That's the nature of an emergency. If I empty out some specially earmarked emergency fund, I don't tell the doctor to quit taking the bullets out of my spleen because I'm tapped. "Sorry, can't touch my HYSA!" (HYSAs are another butt bug of /r/pf)
What people mean by "emergency fund" obviously is their "don't stupidly overdraft your checking account fund", but they never spell that out.
