Similar to a male cuckold, but in this case they're even lower than that.
Backup simps are men who are used by women as a emotional luggage or at times someone they can lean on, very rarely are backup simps able to get the girl they keep simping for, the girl on the other hand has multiple bakecup simps she can use.
>Oh I had a date with this girl I just met and it was so enjoyable for both of us, I tried to be as nice as possible
>But for some reason on the 2nd date she keeps calling me a friend, I guess I have scored high, huh?
>I've talked to her for a couple months now and she's always complaining about how guys's cheat on her and what not, how terrible!
>She wants to go shopping with me, I paid for it all. But it seems like we're still not together.

Rinse and repeat she probably does the same with 5 or more backup simps.

Your partner lies on his back, his legs straight out in front of him, a pillow under his head so he can watch the action. You straddle him with your head facing his feet. With your hands on the floor for support, you back up onto his penis. He holds your upper thighs or butt tightly while you thrust.
