greenskins 

Orcs and Goblins, and related creatures (including Space Orks, Gretchin, Hobgoblins, etc.). It's apparently exclusive to the Games Workshop range of games.

If Orcs really existed, this term would probably be considered racist (especially since some Orcs, the Black Orcs, do not have green skins in Warhammer).

The fortress was besieged by a ravening horde of Greenskins.

greensleeves 

As is a reference to having sex on a lawn and the resulting green grass-stained clothing, greensleeves may also be used in a broader context to generally mean having sex in public.

The risk of being watched while going greensleeves during a music festival could be a Porn theme/fantasy.
