I think people started conflating egg punk with both weird punk and devo core at some point, where I would typically think of egg punk as the intersection of those micro-genres. The meme that named the genre presented all these bands on a chain/egg spectrum, with the Dumpers at like 3/4 the way to full egg. So, by that logic even, like, Warthog was a little egg punk. Anyway, I think that spectrum both highlights the point that egg punk cuts across weird punk, but it also served to muddy the waters in making the distinction, which is probably why folks are too loose with the term these days.
In any event, I feel like “lazy” is the wrong word here. Because it’s not like some kid churning out the most derivative of egg punk is failing to work hard—they’re just failing to be original.
