The act of a female shitting into a condom and freezing it, creating a solid shit "block". The male then inserts the "block" horizontally into any entrance of a female. The male then fucks that hole until the "block" has been "busted". This means physically breaking through the wall of shit with your penis. This may take a while, needing the shit to slightly melt, or using external tools such as a sex toy for fast busting.
Bob: "Hey Joe, your penis is sooooo weak!"
Joe: "It is not... I did the "British Block Buster" with my wife the other day!"
Bob: "Damn nevermind i guess."
Typically used as an alternative for those of the older generation who are still stuck in 20th century, but still want to ask their partner to "Netflix and chill." Instead of committing to a $8.99 per month subscription for Netflix to have sexual relations with one's partner(s), by "making it a blockbuster night" they are only submitting a one time lesser payment for a movie. This movie will be an extremely boring one, but it serves simply to provide background noise while the 2 (or more) engage in sexual relations.
Old Partner 1: Hey girl(s), you sure turn me on. Netflix and chill?
Old Partner(s) 2: I'd/we'd love to, but $8.99 per month is too expensive. Let's make it a Blockbuster night!
Old Partner 1: Wow, what a great idea! That way, we don't have to adapt to today's standards of movie watching, and we don't have to pay $8.99 per month for a Netflix subscription!
