I mean... kinda? She's dumb. They're both dumb. They're also both very strong, talented, and essentially royalty. So while it COULD be that she's emphasizing what she says, from what I recall (she doesn't get nearly enough focus in the ln, imo) it's just kind of a weird speech thing she does. Like -poi and such. I could be wrong about that part since I didn't (and can't) tl, but this is just coming from reading the whole work.
It could also be that this one actually IS 'fuck you' and the rest are just her being weird.

He's muscular, but not large. Without his shirt, he has serious definition and obvious power, but with his clothes on he just looks like a giant beanpole. A more accurate term in english would probably be 'wiry'.
@Snowolf
rudy is stronk but will never reach kazuma tier confidence. never.
@Cellulanus
while tanned dog and cat would be supreme, sadly no. you probably though that cause a bunch of the beast race ARE tanned. which is weird cause they live in such heavily forested areas.
