1.
An endeavor, adventure, trip, or challenge set upon, by men, that is extremely difficult, dangerous, and quite possibly foolish. Body hair becomes a qualifying factor for the leader of said mandeavor, and may be challenged by another for alpha male status by a creative chest/back shaving contest. Designs are judged by uniqueness, difficulty, and cleanliness.
Climbing a rope to the moon, wrestling a giant squid, drinking Robert Downy Jr. under the table, going on tour, buying a new car, getting lunch, or just paling around are all perfect examples of Mandeavors.
