Marci Day is a special celebration that by coincidence coincides with a particular phase of the moon. Ancient tradition places Marci Day whenever the moon is neither full nor new but somewhere in between. The history of Marci day is dubious yet noble. It inspires people of all creeds, species, and food preference to dine out, stay in, and just give in to all sorts of pleasures. The giving of small gifts of appreciation is not discouraged on Marci Day nor is the ignition of displays of pyrotechnics.
Joe: "What are you doing for Marci Day?"
Moe: "I'm going out and getting hammered and exposing myself in public, what about you?"
Joe: "I'm going celebrate with dancing around an aluminum pole, an airing of greivances, and feats of strength!"

When you diddle a man's grapes with the tips of your fingers in a rhythmic motion - usually while a "deedle deedle deedle" noise occurs in the background.
Dude, I got this chick wasted at the bar and she totally gave me a Marcy handshake in the handicapped stall of the mens room!

Mrs. Marcy is the most amazing person ever. Mrs. Marcy cares about you so much but no one sees that :(

You’re so lucky if you ever get a chance to have her in your life some way.
Don’t take her for granted. She’s everything

-OGBC
Everyone takes Mrs. Marcy for granted, she’s so much more than that.

A 90's alternative band that never really caught on. You don't need to know who they are. They had one decent-selling album then spiraled into non-existence. Received some radio air for their single Sex and Candy. Mellow sound, good to listen to while chilling or smoking.
John: I'm really into Marcy Playground these days.
Mike: Who?
