I try and call them all by their proper names, but do tend to lump a lot of the sunfish species I'm not real familiar with as "bream" (like the Pumpkinseed, Longear Sunfish, Redbreast Sunfish, & Orange Spotted Sunfish).
Growing up I called (or actually "learned" to call) Freshwater Drum ..... White Perch and I heard Crappie called "Newlights" (but only by my Grandpa). I never actually used that nickname, myself.
