Top Definition
A new quality brand of the hardcore music and lifestyle. In an attempt to be the most extreme form of hardcore, its popularity is growing. Soon, the hardcore scene will be filled with young teens ready for the brutality. Describing YETICORE, you need to use metaphors, Like, "Pooping out road spikes", "eating bees", "cutting your eyelids off", and "farting liquid nitrogen".
Example of YETICORE is eating a handfull of nails.
