Input: Text: this actually happened during the summer, but it's recently been brought up again.

my son is 8 years old, he came to me and asked me "what does masturbate mean?"  he heard it on a youtube video and was curious, nothing wrong there.  well, even though i knew i shouldn't lie about things like that but i thought 8 was really young to know what that was, so i told him it was when you prank someone really well.  i thought that was that.

well, later on i got a knock on the door from a local kid who plays with my kids from time to time.  she is maybe 11, and frantically trying to explain to me how ian was saying something bad..... yeah..  crap.  

i called him in, thanked the little girl for telling me, and asked him what he said... it took a little bit for him to calm down, but he described what could sort of be a lame attempt at a prank, and he thought he'd congratulate himself by yelling out "aw yeah! i masturbated you! i masturbated you! i masturbated you so hard!" at the top of his lungs.  well, he now knows what the meaning of that word is, got really red faced and had to apologize.  but i have a really fun story for when he gets a girlfriend.

edit: spacing

TIFU by giving my son the wrong definition for masturbate.
