Belushi Speed Ball has a cult following for its headbang-inspiring riffs and tongue-in-cheek lyrics, complete with Spongebob Squarepants references [...] Specifically, the band is a part of the “Pizza Thrash” subgenre of thrash metal, a semi-derogatory name for bands that lean on cultural references from the ‘80s.Spongebob Squarepants aired - as a sneak peak - on Nickelodeon on May 1, 1999, and officially premiered on July 17, 1999.
But the name of the band itself is a valid 1980s cultural reference.
