Your love of the Millers is probably a complex thing, shaped by the many ups and downs and events over the years watching your club.
Here, with tongue lodged in inside of cheek, is a list of feelings, moments and knowledge that make up the anatomy of being a Rotherham fan.
1. You can't help but glimpse over at Millmoor every time you walk up to New York Stadium.
2. Christian Negouai is one of your most hated players of all time.
3. You wince every time you hear Andy Scott's name.
4. You now regularly use the term 'laid siege' in every day conversation.
5. You know a Sheffield Wednesday fan who lives on your street.
6. You got caught out without a jacket on a sunny day at Don Valley Stadium.
7. The mere mention of Trevor Kettle's name makes your blood boil (no pun intended).
8. Every season you say 'This is the year we will have an FA Cup run'. It never is.
9. Danny Bergara is your favourite Uruguayan, despite his disastrous spell as manager.
10. You have this episode of Chucklevision on VHS.
11. You still get starstruck when you see Ronnie Moore in Bramley Morrisons.
12. You spent hours watching the live webcam of New York Stadium's construction.
13. You reminisce about the 2013/14 season. Regularly. Like at least twice a day.
14. You knew the stewards' drill when 'Inspector Meadows' got called to Millmoor.
15. Love or loathe Steve Evans, you can't help but smile at this.
16. You partied in Leppings Lane twice in six months while the other three sides of Hillsborough emptied in world record time.
18. You refer to your favourite player by their nickname. Alfie, Sedgy, Revs, Tiger, Prings, Raggy etc.
20. You were bursting with pride when the Millers won the Auto Windscreens Shield on their first journey to Wembley in 1996.
21. You retweeted this tweet from Ben Pringle.
