The 29-year-old Crowder — the son of former Dolphins defensive lineman Randy Crowder — retired from football in 2011 after being released by the team.
The former player's frank but embarrassing confession went viral on YouTube Tuesday after his appearance on an NFL Films Presents segment about players' and coaches' hidden talents.
For the outspoken Crowder, his special skill was taking a leak on himself – for fun.
"I never went to the bathroom in the toilet," he unabashedly declared. "Every game I peed myself. Six years straight I peed down my leg. I would just be in the huddle and just... pee."
A graduate of the University of Florida, Channing Crowder was the Dolphins' third-round pick in 2005, the Sun-Sentinel reported.
He took part in a total of 82 games, and according to Crowder, he relieved himself on the gridiron during every one of them.
