An Xfreak, is an Ecstacy Addict. Ravers and Clubbers are commonly mistaken as Xfreaks, due to the connection between Raves and Ecstacy. However, some Ravers and Clubbers do use the drug. Xfreaks can be identified by their addiction to Ecstacy, the possession of it, being easily pleasured (touched on the arm, brushed up against, etc.), and being dazed.
There have been rumors stating that when high on Ecstacy, you can OD on water, oxygen, and many seamingly harmless things.
