The motto of FJLs of regretsy.com
Club Fuckery began as a secondary, passworded daily post in the regretsy blog. The password was different every day, but announced on the regretsy facebook page. Many people were butthurt that they did not know the password, so it was eventually changed to cf4l for all Club Fuckery posts.
CF4L can be used to recognize other FJLs offline, and it is common for CF4L to be sneakily formed with letters in craft stores or similar.
"oh, never mind..."
