Common examples include a skater attempting a trick off of a:
stair set, ledge, rail, or anything else high enough to rip your balls off, and ends up getting blasted in the: nuts, rectum, scrotum, taint, etc.

So basically your a little wiener impaled by stick. (just like a cordog).

Now all you need is a little mustard.
