When you club so hard you can't feel your toes a full 24 - 48 hrs after raging. Some of the time due to the shoes you're wearing but mostly because of going too cray cray. If raging becomes frequent, your toes could develop a chronic habit of feeling numb to the point when they fall off. Most commonly found where alcohol and EDM are abundant.
Last time I went to Vegas with Penny, she developed such a bad case of rage toe she couldn't feel her toes a full 2 days after. No matter how much she iced them or put them in hot water, they wouldn't come back to life. Moral of the story : rage on!
