For me, typically if the language is not personally directed at me ("That's a #$*#(* foul!"), but still falls under the foul language category and is public in nature, I go simple T. If it is quiet enough where maybe a player or two heard it, I would likely just verbally reprimand the player. If it is directed at me personally ("You're a $*(*#ing idiot ref"), some sort of slur, and public, that is when I would move toward an ejection. If something is personal, but private, it would be a gray area on what to do. Your mileage may very.
