Wallo notoriously went to prison at age 17 for armed robbery and then did 20 years.
During his Million Dollaz Worth of Game podcast, he spoke about the first time he saw someone drop the soap at the first adult prison he served time in.
It was at SCI Dallas (the "Pink Palace") in Pennsylvania, a facility known for homosexual activity.
According to Wallo, once he heard the soap hit the floor, one of the old heads started making like the Mystikal track "Shake Ya Azz," which caused Wallo to "clutch" his own soap as tight as he could.
"This is a scary moment for me," he said, and then confirmed that's pretty much how it went for 20 years.
