I believe that the entire motto was: "Axis Forever Swimming" In all seriousness, I would've been more than okay with something traditional like... "Wet-Pants Victory!!!"
I'm not sure who was leading it, I'd have to sift through the inbox, which would mean that I have an Axis hull laying around here... "Wet Pants Victory" was from Herr Fleugel If it comes to adult diapers, I'll just buy a Derflinger hull to use for a bedpan instead
