First synchronize your taunts. As you can see, I always went from Top to Middle to Low - it is convenient for you.
I suggest NOT using the extra fancy stuff like, "The EFC is low, let's kill him". Your enemies might have a better chance of spying on it. And what if you mess up?
"[TEAM]The FFC is low, kill that ******"
"[TEAM]The FFC is top, kill that ******"
