(NEWSER) – The Portland teen accused of peeing in a city reservoir on Wednesday insists he didn't do it—in a relatively NSFW defense.

"Yeah, it's f---ing retarded, dude," 18-year-old Dallas Swonger tells Vocativ in what the site calls an "expletive-filled interview" given as Swonger smoked a Newport cigarette. "I didn't piss in the f---ing water."

He explains that he did urinate, after a night of skateboarding at Mount Tabor Park, but he did so against the wall of the reservoir, not into the reservoir.

"I was like, 'Dudes I have to piss so bad.' So I just went over to the wall. I leaned up against the wall and pissed on it. Right there on the wall, dude. I don't know else how to describe it."
