You have to admit there are so many different acronyms for bikers and not everyone knows what they mean. Biker abbreviation can be on a patch or a shirt or just anything really. You really want to know what they mean before you wear them. For example don’t wear a shirt to a professional job or church that say DILLIFAF because you may not be welcome back. If you do not know a meaning of something just ask a biker because they are happy to explain to you what something means.
