Henry Weaver says he has lived on his family's New Tripoli farm all his 69 years, though he spent a lot of time on the road when he worked as a truck driver. "I've seen a lot on the highway in my time," he recalled.

This is something different, though. Weaver on Friday was involved in a strange road rage confrontation, one that a Pennsylvania State Police report summed up in one vague sentence:

"The accused [Weaver] and the victim got into a road rage argument, leading the accused to defecate on the victim," the news release said.

The brief post on lehighvalleylive.com was shared across social media and on websites including The Drudge Report, with readers asking why and how it could have happened.

Weaver said he doesn't have a computer or cellphone, but that he has gotten a number of messages asking about the incident. On Monday, Weaver, reached at his home, offered a blunt, matter-of-fact explanation.

He called the situation the regretable effect of irritable bowel syndrome -- a common, chronic disorder affecting the large intestine, according to the Mayo Clinic.

"I've put up with it for years," he said. "You get worked up and you're going to have to go. ... I couldn't control my bowels. And he was right there. And it's just as simple as that."

It started Friday morning -- state police said at 8:45 a.m. Weaver said he was on his way to the doctor's office.

"I was having a bad day," he said, "and it got worse."

He said a car pulled out in front of him on Route 309, startling him, and he got angry and followed. They stopped near the intersection of 309 and Route 100 in Heidelberg Township, per state police, where Weaver said the two men got out of their cars and exchanged words.

Weaver said there was no fighting or physical contact, but the two were standing close together. He got stressed, and then, he said, it had to happen -- he couldn't control himself and wound up going on the other man's pant leg.

"He was right against me. He was right there," Weaver said. "I had to drop it. ... He just got me worked up. Something was going to happen. I could have easily have missed him if I had turned around but it happened then."

State troopers in the Bethlehem barracks did not return calls Monday seeking more information. The initial release accused Weaver of harassment and said charges would be filed in district court in Slatington.

Nothing had been filed as of Monday morning and it was unclear if any pending charge would rise to the level of a criminal offense.

Weaver said he regretted what happened.

"Most people who know me know I'm chill," he said. "But you really have to do something to get me to that point.

"I'm not proud of it," he later continued. "I messed up. It happens."
