Wulf is much as chafing, except it is only focused around your ball sack or between butt cheeks. To catch a wulf you have to be sweating a lot and moving around, sitting down on a cold piece of ground usually doesnt help either. Wulfing
causes this itchy and annoying feeling, almost like a wulf bit you. You can think of it in the way that you have a wulf constantly biting into your butt or balls. To get rid of a wulf one must run faster than him, which is impossible, or you can go to the ocean and put some salty water into his snout and drown him.
1) Oh man, I've been busting my balls all day running around sweating, then I sat down on a cold marble stone and caught a nasty wulf.
2) Look that kid is walking funny, I think he's got a wulf.
3) It sucks to take your girlfriend out for a dinner, while you have a wulf, that way you have to pay for 3.
