1. (noun) any highly gelatinous/glutinous, substance with a largely clear (transparent) composition used in the context of sexual activity.

2. (tr. verb) to expose to, affect by or submerge in ecto.

3.
A style of music characterized by female singer songwriters with an emphasis on melody, and an unaggressive (although some say pretentious) style. Good examples are Jane Siberry, the Indigo Girls, Sarah McLachlan, and Kate Bush.

The name itself is from the Happy Rhodes mailing list, but has since become a term in its own right.
"Yeah, she was a goth until one day she came wearing a camisole and dress with flowers on it, and she's singing songs about how California wants to be New York or something. She's gone totally ecto."
