How many times when you were a kid did you want to tell siblings to just f**k off? Probably ever single day of your kid life, right?  But for most of us, the fear of repercussions for using such filthy language was usually enough to keep us from using the devil's language.  This one kid, though, was granted permission to use the filthy words and decided to take full advantage!

Watch below as two brothers fight about something stupid in the way that all brothers do.  Big brother pisses off little brother, who then turns to Dad and asks, "Can I just swear once?"  Surprisingly, Dad gives the OK, and little guy fires off a healthy "F**k you, Jack!" to his big brother.

Bad parenting? Probably. But we sure enjoyed it!
