I'm plum bereft of creative energy today, so I'll leave you with what I say about it in my book (in the hope that you'll want to go to Amazon and buy it right away):
Read about "pisscall" on p. 31 of On The Road (1976). Isn’t that a great and fun passage? I wrote something I thought was scholarly and profound for this admittedly long entry, but decided after reading it that it was best said like this: goof on your friends whenever possible and pee wherever you happen to be when the urge strikes. That is, live! And have fun while you’re at it. If your friends can’t take a goof, get some new ones. If you can’t bring yourself to pee except in dumb white bathroom machinery, perhaps you might ask yourself why.
Go outside and pee. Now.
 Sorry. I just couldn’t leave you to your own devices for finding this one because you absolutely have to read this passage as part of your beat education.
 Or pee on a jellyfish sting to ease the pain (a gratuitous pop culture movie reference).
