Inspired by this question on SFF.SE.
I recently discovered this video, where an Italian man adds Nutella to the mix1, to his great excitement.
However, I'm not clear on why he did this; I couldn't see a significant difference in the reaction (although my view was somewhat obscured by the condom). What does the Nutella add to this reaction?
1 Do not watch this video in a public place without headphones on (or the sound turned way down); he gets very, very excited when his
abomination experiment (literally) blows up in his face
