Walk For Mankind

A fundraiser in the 70's where a person gets pledges of $ for the amount of miles they walk. It's a 22 hour walk. People put out water, hoses, apple juice & donuts for the walkers.

I did the Walk For Mankind in 8 hours with no previous training & my feet were so sore but at least I completed it!

mangini 

To respond to a piece of good news with animated, speechless, exuberant excitement. Named after musician Mike Mangini, who was rather pleased to be selected as Dream Theater's new drummer.

"When Edna found out she was going to be a mother, she manginied so hard and for so long that she almost gave herself a hernia.

Manual Mangina 

A Manual Mangina is when a man (or dildo wearing woman) uses heir penis (or phallic device) to manipulate time and space. In order to do this, participants need to stand naked in a mildly populated area and whip heir phallic ownership up and down until enough momentum enables the cock handler to catch their phallic device between heir legs and hold it there. Causing the owner of the phallus to look like a girl (thus the appearance of the Mangina) laughing or name calling might ensue, or even applause if the owner can manage the Mangina in a single thrust.

" I call this the Manual Mangina!"

Mangineering

The act of creating or repairing useful items employing the materials at hand. Mostly practiced by men, it is often criticized by those who aren't able to come up with solutions anywhere near as practical. Common mangineering supplies include duct tape, bailing wire, zip ties, and PVC pipe.

Sally and Tom were stranded in the middle of nowhere because their car wouldn't run. Sally stomped her feet and shouted "Girl Power!", but for some reason it still wouldn't run. Tom used his mangineering skills and fixed the problem with duct tape while Sally rolled her eyes.
