1. A biological term meaning the shedding of an outer hard layer(like cuticle), such as done by a snake or a crustacean when it's molting.

2. A strip performance, as done by an ecdysiast.
Snakes are known to perform an ecdysis in order to grow a new outer layer. Interesting, but I'm more interested in the other form of ecdysis performed by females of the human species.

Slang term for MDMA (3,4-methylenedioxy-N-methylamphetamine) which causes users to drink water, touch themselves and dance like a prick. You can tell someone has ingested such substance by the pupils looking like big black plates , they look as though they are trying to eat their face and they are excessively sweating like a rapist in a brothel. The term "eccy" is more commonly used in Scotland and northern parts of Britain.
