A 'jungle munchkin' is that friend who can swing from tree to tree like nobodys business but is around 5' tall.

The jelly munchkin is the same thing as a jelly doughnut except it is done with a midget.

Kids between the ages of eleven and fourteen who believe they are rebels or street kids but who really are white suburban children who are a nuisance to society. They believe they are thugs, but are just little kids causing trouble.
