Even though you can find even worse sexual innuendos and ERP type things already without the /doze emote from beds only (as far lying down.) we already got an answer a while back when the emote was first going to be introduced.

Personally I'm against their outlook and decision on the matter, I mean the new /sit /cpose emote... have you seen the things people do with that? Also... the bottles of Realm Reborn Red... go check on over at the "Show your Roe" thread, and be quite surprised around some of the last few pages.
