What? Can someone explain what this means?

From the latest hotfix notes

What the heck is this all about?

While D.I.S.C.O. may be fun for some, dancing is now prohibited within the vicinity of the Chamber of Heart teleporter.

D.I.S.C.O. is a toy that, when used, makes toons within a certain proximity dance. I assume it means it can no longer be used around the teleporter for the Chamber of Heart.
