fastarlini

The term “fastarlini” is a word created by Expressions Oozing. It was originally called “fastard” which was a nice way of the saying the swear word “bas*ar*”. However as Expressions was so angry the word “fastard” was not adequate enough so he decided to add the word “lini” to make it sound more aggressive.

Sol Campbell you fastarlini
