Bakusho (爆笑) literally translates to ‘explosive laughter.’ While learners often use it to mean ‘laughing out loud’ (LOL), it carries a specific cultural weight that signifies a collective, uproarious, and thunderous burst of laughter shared by a group—not just a solitary chuckle behind a screen.
When I first moved to Tokyo, I made the classic mistake of sending a text to a friend using ‘bakusho’ to describe a funny meme I saw. I thought I was being casual. My friend, however, asked if there were a dozen people around me laughing, too. That’s the nuance of Bakusho: it implies an intensity that fills a room.
The Evolution of a Word
Historically, the dictionary definition of Bakusho is ‘a roar of laughter from a crowd.’ In the digital age, however, the meaning has blurred. Much like ‘literally’ in English has shifted, many young Japanese people use Bakusho in casual text messaging, though purists still cringe at it. Understanding when to use it versus when to use simpler terms like waranai or haha is key to sounding authentic.
Pro-tip: Avoid using Bakusho in formal or business settings. Even though it’s an ‘essential’ word, it implies a lack of composure. If your boss tells a joke, a polite smile or a soft ‘kekkou omoshiroi desu ne’ (that’s quite funny, isn’t it?) is far better than an ‘explosive laugh.’
Common Mistakes Foreigners Make
The biggest trap is assuming Bakusho works for every funny situation. If you’re alone watching a show and find something funny, saying ‘Bakusho!’ sounds like you’re over-dramatizing. It’s a group dynamic word. If you find yourself wanting to express that specific urge to snap back at a joke, you might want to learn about Tsukkomi-iretai to better contextualize your comedic timing.
The Slang Variations
In internet culture, Bakusho is often overshadowed by ‘w’ or ‘kusa’—a concept we’ve explored in our guide to Kusa-hayashiteru. However, when you are in a face-to-face social setting, Bakusho remains the gold standard for describing a moment where the entire group has lost their cool and dissolved into genuine, thunderous amusement.
“Ano toki, minna de bakusho shita yo ne!” (We all exploded in laughter at that moment, didn’t we?)
Notice the emphasis on ‘minna’ (everyone). Bakusho isn’t just about the volume of the sound; it’s about the shared experience of the joke. Use it when the air in the room changes, when the conversation hits that peak level of humor where everyone stops their activity and just laughs. That is the true essence of Bakusho.
