Colonel Watts: Go down to the Supply deck to see if there are any sound-powered phone batteries.
Corporal: Sir, yes sir!
Watts: *chuckles*

Power phoning
Someone making a loud condescending phone call in public, especially as a way to show off.
Power phoning I wonder if there is someone on the other end putting up with being power phoned, because if someone tried to say that to me I'd tell them to try and say that to me in person, and then hang up.
