Never Live It Down: Ultra-violent Soren is constantly razzed by the rest of the Foxhound Pirates due to his apparent soft spot for Smoker's second-in-command Tashigi. He never harms her during their run-ins despite being far stronger. The others jump all over it because he is usually quite brutal to most enemies of the crew, especially Marines.
Naruto will never let Vivi forget that she reminded him of a stripper when they met. He even had a stripper pole installed in her quarters.
What an Idiot!: Naruto's idea of keeping the ship sailing straight is to not touch the helm at all. Nojiko quickly calls him out on this.
