City slickers...
Obviously poison oak. Plenty of good men go out and work in that stuff up to their neck...get covered with it, and simply go to work the next day. Don't scratch it any more than you must, wash entire body with dish soap asap, drinking alcohol and/or exposure to hot shower will light it up!

I know all to well how much a case of this stuff can bother a guy, but it really isn't anything worthy of crying about.
