Laughing Smith (Wet Farts) is a psychological nightmare
While Liquid Ass hits you with sharp chemical sewage, Laughing Smith went a totally different route with their Wet Farts formula: pure, gross realism.
Instead of smelling like a broken bathroom, Laughing Smith's spray mimics the warm, humid, unmistakable scent of someone having a severe stomach accident right next to you.
And that's why it works so well: nobody suspects it's a joke spray.
Reviewers constantly mention that when you sneak a spray from Laughing Smith under a friend's chair, they don't yell at you for pranking them. Instead, everyone in the room awkwardly looks around and starts trying to figure out who just painted their pants. It's hilarious, but in a much more uncomfortable, slow-burn way.
Just watch out for the bottle itself—a few people mentioned the nozzle on the Laughing Smith bottle can leak a bit. If it gets on your fingers while spraying, congratulations, you just pranked yourself.
Liquid Ass smells like an actual crime scene
There's a reason people have been using Liquid Ass for over ten years. It doesn't just smell bad—it makes people instantly question their safety.
Reviewers keep describing it as a mix of a porta-potty sitting under the 90-degree summer sun and a broken sewer pipe in a closed basement.
The biggest selling point here is speed. One quick spray and the odor hits like a brick wall. People don't even pause to ask what happened—they just gag, cover their faces, and run out of the room. It's perfect if you're filming in a living room, hallway, or elevator and need instant, high-energy panic.
The only real danger? Do not get this on your clothes or couch. Dozens of angry buyers warned that the smell bonds to fabric like superglue and won't come out even after multiple washes.
So, which one should you buy?
It really comes down to where you're filming—and how long you want to deal with the smell afterward.
- Go with Laughing Smith (Wet Farts) if you want that ultra-realistic stomach disaster reaction, but need the stink to clear out quickly. It hits hard and fast, but if you open a window, the air usually clears up in about 20–30 minutes without permanently ruining your carpet or clothes.
- Go with Liquid Ass if you want instant, high-energy panic for Reels or Shorts and you don't care about ruining the room. Just be warned: this stuff lingers forever. If you spray it in your own bedroom, you'll be sleeping in that sewer smell for the next three days.
