My friend calls a loaded aircraft carrier a ‘key defensive position’ as a joke and refuses to call it an aircraft carrier.
One strategy we use is for complete naval domination of the mediterranean, since it helps to hold africa and leave untis out of southern europe, so we call southern europe the soft underbelly since its always undefended.
Any time 2 massive forces collide for strafing where both of them will surely be killed (usually germany killing off a mass of russian tanks with whatever they ahve around), we say ‘MU-TUAAAL DESTRUUUCTIOOOOOON’ in weird deep voices. I assure you this IS the corniest thing we do. :-P
We have a lot weirder terminology for risk though. We played once at school and nobody knew what we were talking about because we kept calling things ‘bitchfights’ and ‘poopshoots’.
