"Because you'd be the groom, idiot!" Now Bulma's getting that grind in her voice, the kind that shows true irritation at what she's yelling about. This is a pretty normal marital spat for them, but she's already aware of the people around them (that aren't Yondu) beginning to shrink away the louder she gets and the more she crushes closer to Vegeta's face in doing so. Now whether that's because they aren't fond of her tone, or they know Vegeta and maybe aren't sure how he will react... Bulma doesn't care enough to really check.

Thankfully Vegeta doesn't give her time to ask Yondu what the hell he means, reaching for her hand and telling her to stop, as she's already shaking him off to stab at the chest plate of his armor with said finger.

(She's easy to distract, at least.)

"Stop telling me what to do! That's my job!"
