Do we have regressive and shaming names for excessive water drinkers? Excessive breathers? Excessive readers?

Those aren't common things to be. We have regressive and shaming names for the excessively wealthy, the excessively macho, the excessively progressive, etc.

All things in moderation.

No, no, and yes.

There are few, if any, shuttering themselves away from regular social interactions due to an addiction to water or air.

The appearence of doing so because of a porn or more general book compulsion is more commonn.

So what's the regressive and shaming name for excessive readers?

Aside from four eyed bookworm et al you mean?
