To understand a Vegeta... You gotta be one...
King!!! Pah!
Loser.
Translation for non-Vegeta-Go-Speakers: Vegeta 13 and Vegeta 18 showed their compassion to Vegeta 10, but he prefered to ignore such aggressive sentences. But then both Vegeta insisted in calling him “weak”, “humble”, and even “loser”, challenging his already tattered sense of pride.
At the end, Vegeta 10 decided to hit the weak spot of the other Vegeta, thus being the only King of the Saiyans of them, much to the discomfort of the others. But the last laugh belongs to Vegeta 18, who claimed to be the strongest and that he’s gonna crush also his counterpart from Universe 13, as being only half-strong compared to him. That’s it.
I only understood the last part... I guess you need to be a Vegeta to get it...

Note: Vegeta 18 saying to be twice stronger than Vegeta 13 is only an assumption from him. No "canon" power indication is given here.
