As first mentioned by Patrick from "Spongebob," It is the act of a woman allowing a man to engage in anal pleasures. Usually given in exchange for an invitation to an occasion involving getting dressed up or fancy dinners (i.e. Fraternity formals, Proms).
Tim: "she has been bugging me for a week to let her be my date to formal next week. But if she wants to go, she's going to have to let me get some wumbo action in so there is something in for both of us."

Wumbo is more than just a word, it´s a style of living, of seeing what´s going on. It could be characterizised as something between past drunken aphathy and bacardi induzised screaming the sun out of your ass. Everyone should have his own WUMBO just to analyse what´s between you and the things around you. WUMBO lives not in the past, not in the future; he lives now and it´ll not be payed to ignore. He is a fact.
Wumbo is also a synonym for rock´n roll in a big box lady, cru, chruett, ...
Let´s WUMBO!
Wumbo is the godfather of bacardi and rockes your sweet soul, baby.

The wumbo-sized lollipop was as big as a cow!
