Andrew Befumo Jr. and the Family Formula Behind the Boom
Short Biography
Andrew Befumo Jr. is a New Jersey-based creator. While most people know him as A.J., one half of A.J. & Big Justice (the Costco Guys), that wasn’t the name that put him on the map. What helped him gain notoriety was the use of fun videos where he created entertaining content along with his son, Eric. Their Costco reviews (big reactions), along with catchy lines and tags, also contributed to their quick growth online. Andrew was also a wrestler prior to being an internet sensation, so he had experience entertaining and could produce bold, camera-ready performances as well.
From New Jersey Wrestling to Viral Creator
Andrew Befumo Jr. distinguished himself from others because he had an idea about how to entertain others before becoming a viral creator. His years of experience wrestling taught him about building energy, creating catch phrases, and keeping people engaged. Those skills gave him the chance to make awesome short video content that is loud, fun, and sticks in the minds of viewers.
A Family Brand That Connected Fast
Another element of Andrew’s success is the family aspect of his videos. Videos of him and his son Eric’s father-son relationship are warm, humorous, and authentic. He and Eric’s father-son chemistry created a connection with viewers. Their Costco excursions, food reviews, and their own systems for rating items (“Boom” and “Doom”) made their videos easy for viewers to watch and share. This ultimately led to the phenomenal growth of their content.
He Expanded Beyond Short Clips
Since he has become so successful via so many short videos, Andrew has truly turned that online attention into a larger entertainment business by appearing on television, releasing music, and now even joining AEW in wrestling. Not only did Andrew become famous through a growing trend, but he also created a greater, more public persona for himself with family-based content, a strong performance presence, and personality.
