Margera was born in West Chester, Pennsylvania, the son of April (née Cole) and Phil Margera. He is the younger brother of Jess Margera and nephew of Vincent Margera. His grandfather nicknamed him "Bam Bam" at the age of three after noticing his habit of purposely running into walls; over time, that nickname was shortened to "Bam" by his schoolmates. He attended West Chester East High School and cites his friendship with Chris Raab as his only reason for attending high school. He dropped out after finishing his junior year, citing Raab\'s expelling as his motive.\n', 'Margera then received his GED afterwards.\n', '
Margera began shooting videos of himself and his friends skateboarding and doing stunts, which eventually turned into the CKY video series. He independently released CKY. CKY2K, CKY3 and CKY4 have also been released. CKY stands for "Camp Kill Yourself", a name shared with his brother Jess Margera\'s band, CKY, who themselves named the band as a tribute to the film Sleepaway Camp. These early videos feature many of Margera\'s friends, including Ryan Dunn, Brandon DiCamillo, Rake Yohn, Chris Raab, Brandon Novak and others who form a loose collective known as the CKY Crew. The history and relationship between the video and band projects is heavily interlinked.\n', '
Following the CKY success, former Big Brother editor Jeff Tremaine noticed Margera\'s videos and drafted him into the team which would eventually become MTV\'s Jackass. Margera and Ryan Dunn became mainstays of the cast while other CKY crew members played supporting roles to various degrees. Margera went on to appear in Jackass: The Movie, Jackass Number Two, Jackass 3D and Jackass 3.5. Several skits in the first Jackass movie were CKY style pieces filmed in and around West Chester, but similar scenes in the second movie were removed after the arrest of Margera\'s uncle Vincent Margera on suspicion of inappropriately touching two minors.\n', '
