Glimmer: someone really should tell twilight to stop testing spells on you  
Spike/barb: nonsense darling, I’m perfectly fine with it, especiially since now I look so fabulous! And as I said before, there Is no such thing as over breasts looks at her chest  
Glimmer: why are you talking like rarity  
Spike/barb: I’m not quite sure, after twilight turned me into a girl she hit with another spell, and then I realized that not only was undressed, but I lacked any proper clothing, so I went to work sewing myself and twilight two new absolutely wonderful sets of dresses!  
Glimmer: she made your mind into a copy of rarity’s, great, as if one histrionic horse wasn’t enough, now I have to deal with an overdramatic dragon of all things! shouts over her shoulder twilight!

I feel this caption inspired this.
 

The bigger, the better.

Remember, Starlight, that in the Equestria Girls universe, there’s no such thing as breast coverings. So when you appear in those movies you are not allowed to wear a shirt or a bra.

There’s no such thing as being over breasts. Loving them is forever.

Can this also be considered a VA joke?

Is he talking about size or quantity?
