This is a major insult only used when one has run out of the
normal insults and needs something that will incompass all of the other insults into one big one. One can spice things up by substituting other
words at the end such as, joke in a
hobo's sock, joke in a rabbits ear, joke in a paper bag or even joke in a goats butt crack..ext.
Me- Alvin can i borrow your car tomorrow bro?
Alvin- No man i need it to take my
girlfriend to a play.
Me- Your a "Joke in a hat" you dork.
I asked billy
bob to come to my ex girlfriends birthday
party and that "joke in a sock" said he had to study.
