according to wiki.....
Pepero Day is an observance in South Korea similar to Valentine's Day. It is named after the Korean snack Pepero and held on November 11, since the date "11/11" resembles four sticks of Pepero. The holiday is observed mostly by young people and couples, who exchange Pepero sticks, other candies, and romantic gifts.
According to one story, Pepero Day was started in 1994 by students at a girls' middle school in Busan, where they exchanged Pepero sticks as gifts to wish one another to grow "as tall and slender as a Pepero".
