Glossary of Unfamiliar Terminology

[DaveMack]

Just thought I'd start a thread where terminology some of us (I'm sure I'm not the only one who reads these forums and comes across terms that they are unfamiliar with) are explained.

I think, for the sake of those who might genuinely need help in this area, it is best if this is kept strictly as a "Glossary of terms explained" rather than a chance to sling the sh*t at someone who asks a question.

I'll start the ball rolling by exposing my ignorance:

"Swallowtail" as in MkI Swallowtail. I'm sure it's something to do with body shape, but for the life of me ... I cannot see the diff between a MKI described as a "Swallowtail" and one that is not.
