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

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.
