Traditional- In keeping with the Faith of the Fathers.
Liberal- Outside the norm, practices that have not been generally used by the Orthodox.
Renovationist - Deliberate action to change, revise, water down, or alter what has been taught by the Fathers to fit their worldview.
Ecumenist - Someone who believes: "everyone (denomination) has equal claim to being in the Church. We should band together, blend things in a bit, and be one" or one who thinks the Orthodox should give some leway to Christian communities so we can become one church. There is already One Church.
That's usually what I mean when I throw those words around haphazardly-- being a reactionary, Tradionalist, hyperdox Herman, little church on the prairie, conservative.
