Fellie
Fellie is the equivalent/opposite term for Trammie, not as commonly used and of far more recent vintage than its "sister" term.
Fellie is used, mostly but not exclusively, by players on the Trammel rules facets to describe those who play mostly in Felucca. Like "Trammie," "Fellie" was intended as an insult but is on occasion used in less derogatory senses.
