Feel like people are missing that a) a lot of characters in this story are very good at reading people and b) Floyd's insult could easily have been tailored to piss off a lot of people other than Kaji.
Like this:
1. You say some shit like "'Daddy' will praise you"
A. No particular reaction -> miss, move on
B. They seem mad that you're treating them like a kid or looking down on them in general -> hit, hype that up
C. They react to the word "Daddy" -> critical hit, daddy issues, move on to step 2
2. Try calling them a few variations of what their Dad might have called them
A. No particular reaction -> miss, move on
B. They react to one particular nickname -> hit, bad relationship with their dad, probe for more details and also call them that nickname constantly
C. They react a bit to multiple nicknames -> critical hit, too many dads
D. Same level of reaction to each nickname -> hit, no dad (probe more to figure out if dead or deadbeat)
It's a pretty good strat considering all the back stories we've seen in this series (assuming you can survive the consequences.) You will strike gold often.
