What does AOL inches mean?

AOL inches meaning in Urban Dictionary

A unit of dimension for identifying the length and girth of an erect cock. Utilized solely by guys (usually not always homosexual guys) in internet dating or chat profiles, the system, while not consistent, usually corresponds roughly to 1.5 United states or English system ins. For instance a typical 6 inch long cock becomes 9 AOL ins, etc., although "average" AOL inches length seems to be between 8-9. Regardless of the name, AOL inches are now utilized universally on the web, not merely on AOL any longer.
