Could someone please provide specific examples/explanations of the following terms:

Chug Chugs

Djent Djents


I've heard that Meshuggah has tons of Djent Djents, what are they?

What are some good songs that have chug chugs in them?

Also, what are some good breakdowns, are they like interludes that include chug chugs, or do they have riffs?

How are chug chugs different than riffs? Is chug chugs another word for breakdown? Also does music outside of the metalcore genre have breakdowns, bands like Meshuggah, Between the Buried and Me, etc...or do only core bands have breakdowns (Emmure)?
