A day that has some legitimate meaning behind it (New Years Eve, St. Patricks Day, etc.) but is instead known for lightweights and drunk d-bags who drink more than they should and get sloppy drunk because its "cool man!" St. Patricks Day is such an Amateur Holiday.
On St. Patrick's Day I wanted to have some corned beef and a few green beers but every bar and restaurant was filled with sloppy drunk people in their 20s to 50s who cant hold their liquor. St Patricks day is a textbook Amateur Holiday.
