Here’s what Lucas Entertainment has to say about this scene:
“No, we didn’t spell “nutt” wrong — head over to Urban Dictionary and you’ll see that “nutt” has it’s own entry: it’s when you pump your load into a happy and willing human receptacle. The hot thug Giovanni Matrix is all about nutting, and it didn’t take any convincing that Javi Velaro would be an awesome candidate for him to work up a load with.
I don’t want to mislead you — Giovanni doesn’t cream inside Javi directly (there’s the “money shot” obligation) — but from what I hear Javi is pretty tight in the behind, so I’m sure Giovanni wanted nutt directly inside him. Maybe next time!”
