It’s from fnaf? Don’t tell me you never knew about fnaf?

It’s basically the main mechanic for the animatronics in those games. Springs that can lock to allow a person to pilot the animatronic. A springlock happens when those locks… y’know, don’t work. I’ll let you imagine the rest.

I was making a joke about how that might actually happen if someone tried making pilotable animal mechs lol.
