Maybe he should. Squalo makes some kick-ass pizza, among his other few good qualities.

Now, he's quite pleased with that first part and is about to shoot something like you'd better back, but then Xanxus just has to go and call him a girl. Not to mention bastardizing the name he's hated his whole life into an even more insulting version of itself, and he sees white for a moment.

He could punch the bastard, he considers. Or he could flip the couch over. Both of those things would result in violence, though. So he goes for the third option; with terrifying calmness he reaches out and grips Xanxus' crotch with his metal hand, squeezing it threateningly. Not hard enough to cause permanent damage (yet), but it's ought to be painful.

"Wanna repeat that, Xanxia?"
