I love how someone uploaded a video titled "Virgin asshole destroyed by BBC" to pornhub, and it was a video of Ben Shapiro losing his shit after badly failing at debating one of the BBC hosts.
Those of a vintage beyond even my own will know that it stands for "Broken Biscuit Company", which I believe originated on BBC radio with The Goon Show. Now that's not an acronym, but it is another word that's picked up an unfortunate extra meaning in recent years.
