Wumbo. The word is mention in Season 3 Episode 1 of Spongebob Squarepants, but what does it mean. Clearly it is the opposite of mini, but what is it beyond that? By combining the two words Jumbo and Waddle, you create Wumbo, a complication that causes rather large people to waddle when they walk. Wumbologits study the field of Wumbology, the study of Wumbo. The equation to determine whether or not someone is indeed Wumbo is:

Circumference of the waist
--------------------- x Number of taken to walk a foot
Your Shoe Size

This equation gives you your Wumbo Index number or "Wumbex"
Based on averages, a normal number would be under 5. Anything over 5
means you are Wumbo.

There is also a number of conditions associated with being wumbo, heres two examples:

1. Wumbo by proxy- People who hang around wumbo people so much that they two being to waddle
2. psychosomatic Wumbo- People who are not wumbo but waddle anyway
