To become enraged; to lose one's temper, clothing and power of coherent speech before embarking on a spree of violence and wanton destruction. After the comicbook character who turned from an unregarded geek into a thundering green mass of unstoppable fury.

Whie originating with Marvel Comics loveable monster The Incredible Hulk, the term can also be universally applied to almost any character who undergoes a transformation that drastically upgrades his size, power and level of mass. Often, but not always, accompanied by damage to their clothing or an increased level of musculature. But a straight increase in overall body growth without any added muscle, or a sudden increase in various physical attributes such a womans breast size can also be considered "Hulking out".
When exposed to a full moon, a Saiyan who still retains his/her tail will often HULK OUT into a giant, out of control primate.
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.
