What's a spinblocker exactly?

Question

I've heard a lot about questions I've had that were answered but a lot of them said something about spinblockers and I'm not sure what they mean, my guess is Pokemon that can counter those who rapid spin and such but I'm not entirely sure.

Answer 1

A spinblocker is well, exactly what it means: Pokemon who can block Rapid Spin. Since Rapid Spin is a normal type move, ghost types are spinblockers since they are immune to normal type moves, allowing them to block Rapid Spin.
