It's important to keep an eye out for YOLOers in your neighborhood. A typical YOLOer can often be seen:
raising a 40 in the air while yelling "WOOOOOOOOOO!!!!"
immediately making their presence known whenever they walk into a non-party venue (e.g. restaurant) by talking to other YOLOers at approximately 2.5 to 3 times the normal human conversation volume.
committing misdemeanors under the guise of "living life to the fullest."
