Getting caught "
white-handed" is when someone is caught in the act of masturbating. They could be masturbating to porn, or they could just be having some fun with themselves on the toilet.
White-handed refers to the cum that drips out of their penis and onto their hands if they
don't clean it up right away.
Ethan's mom: So I was going into Ethan's room
yesterday to give him his laundry, and then I caught him
white-handed!
Ethan's teacher: I caught him in
school once! He is such a horny kid...
