Naming Day
From Memory Alpha, the free Star Trek reference.
Naming Day is the day on which male Ferengi are formally introduced to the world outside their family and one of the first opportunities for a young Ferengi to acquire property or make a profit. It is one of the few Ferengi traditions that involve the giving of gifts.
On Rom's Naming Day, his brother Quark replaced his gifts with old vegetables and sold the gifts for a profit. (DS9: "Rivals")
