It's GT vegeta, but the line in my head is from DBZA.
(paraphrased)
V: Saiyans' hair never changes, except for our beards, and moustaches
G: Now I can't stop imagining Vegeta with a moustache
Imaginary V: Moustache *spanish guitar riff*
G: Hehe
Also: this is from a Spanish AU literally called Undernovela. And the songs themselves sound Latin (a lot of the comments said Mexico). Thus I disagree with anyone who might say this is racist
