The act of litteraly ripping clothes off one's own body. The clothes are normally very old and no longer wearable in public or in extreme cases even around the home. The garments usually rip off very easily. Most commonly performed by straight, single men, as they are the most inclined to wear old, worn out, filthy clothes. Hulking out of clothes that are too tight is a common ritual for people still growing and/or gaining weight. Closely related to going party boy jackass style.
These shorts hurt my nuts too much, that's it I'm hulking out.
