Epic Beard Man refers to Thomas Bruso, a senior citizen who became an internet sensation after a viral 2010 video depicted him in a physical altercation on an AC Transit bus in Oakland, California. Wearing a t-shirt that famously read 'I Am A Motherfucker,' Bruso defended himself against a younger passenger who initiated a fight, leading to the creation of the 'Amber Lamps' meme and a series of parodies. The meme typically celebrates the idea of an unassuming older person possessing unexpected strength or a 'no-nonsense' attitude. It remains one of the early examples of viral street justice caught on camera, cementing Bruso's status as a cult figure in early 2010s internet culture.
