An "attempt", usually organized at work by fellow employees, to celebrate the upcoming birth of a MAN's baby. Festivities typically take place in a office conference room and feature store bought cookies.
We will meet in conference room J at 1:00 for Billy's man shower.
A battle of sheer manliness similar to beer pong except that instead of tossing a ball into a cup, one must use said ball to knock over the cups of their opponent. Players must be unshaven and/or wearing flannel shirts at the time of competition. In addition, the loser must lap the spilled beer of the floor like the dog that they are. A game of brute force.
Dave: Hey Jake, why is your arm in a sling?
Jake: Man pong.
A beautiful man that is better looking than most. Occasionally models/ acts. Know to overwhelm people with their stunning looks and obnoxiously well matched outfits.
v. To act in accordance with established masculine roles in a given situation, implying courage and responsibility. Usually used in the imperative, the term is a favorite of police who want suspects to incriminate themselves. Ironically, advice to 'man-up' is usually followed by a promise that it is the least painful alternative.
You signed for a package full of weed, now you need to man-up, and admit that you knew what was in it. It'll go easier for you with the judge.
