"BDZ" is a song by K-pop girl group TWICE, from their 2018 Japanese album with the same name.
The music video is set in a world that was once a happy place where people lived alongside lovelys, small creatures that embodied the love humans had, until evil people captured the lovelys and are keeping them as prisoners, turning the world into a Crapsack World of anger and violence. The Twice members can no longer accept that the world has gone sour, so they must take matters into their own hands to rescue the lovelys and restore love to the world.
A Korean version of the song appeared a few months later as a B-side on the Yes or Yes EP.

Like a bulldozer, like a trope, like a soldier:
- Action Survivor: The Twice girls in their most action-oriented video. For instance, Mina's method of attack against a Consummate Professional law enforcement agent is... distracting him through her cuteness. (sadly, it doesn't work)
- Air-Vent Passageway: Dahyun and Chaeyoung use this to drop a pizza on the boss' desk.
- Big Damn Heroes: Jeongyeon shows up with a bulldozer just in time to save the rest of the girls from being shot dead by the goons.
- Call-and-Response Song: "Like a bulldozer (hey!), like a tank, like a soldier (let's go! let's go!)."
- Care-Bear Stare: The final attack of the lovelys, which makes the bad guys turn good at the end.
- Crapsack World: The result of the villains imprisoning the lovelys and taking away the love from the world.
- Equal-Opportunity Evil: The enforcement goons in the video are noticeably diverse, and the first four we see as the song begins are Black, white, western-Asian and eastern-Asian.
- Head-Turning Beauty: The sight of Jihyo elicits the most blatantly unchaste reactions from the government agents.
- "Home Alone" Antics: How the girls deal with the bad guys, such as when they put wet paint on the stairs to make one of the goons fall down.
- The Knights Who Say "Squee!": The law enforcement agents in the video are giddy fanboys for TWICE, but still have to do their job in maintaining the music video's Crapsack World.
- Laxative Prank: The pizza is implied to have been laced with a laxative to make the boss run to the toilet after eating a few slices by himself. The girls then use a chair to temporarily lock him in.
- Mission Control: Jeongyeon spends the majority of the video overseeing the mission from a computer in the group's hideout.
- Non-Action Big Bad: The man with the red tie is implied to be the boss of the goons keeping the lovelys captive. He is also the only one without a weapon.
- Opening Monologue: Sana (in her natural voice) starts the video by explaining the plot to the audience.
- Schmuck Bait: The boss sees a pizza on his desk and immediately starts eating it without questioning how it got there. The pizza is a trap, placed by Dahyun and Chaeyoung, that makes him run for the toilet.
- Soundtrack Dissonance: Despite being one of the darkest Twice videos, the song is one of their most upbeat, being from the only Japanese album of their bubblegum era.
- Title Track: The song is this to Twice's debut Japanese album BDZ.
- Translated Cover Version: The song was later re-recorded in Korean for the Yes or Yes EP.
- Visual Title Drop: "BDZ" is short for "Bulldozer", which Jeongyeon brings in near the end.
