Japanese Mispronunciations/Yazooka
Joe intentionally pronounces various Japanese words wrong to annoy the weebs in his audience. Sometimes these phrases may also lead to the corruption of the English language.

This is a Joeism

When Joe says this, it's not a reference to any stream. It's just something he says sometimes.
"Yakuza" is a word typically referring to a type of Japanese crime syndicate, which Joe pronounces as "Yazooka" instead.[1] This was particularly often said during the Yakuza 0 streams.
