Screaming O 4B Deep Rumbling Bullet

Small Body. Big Attitude.

If you’ve ever wished a bullet would stop politely buzzing and start actually doing something, meet the 4B Deep Rumbling Bullet. This is the one that skips the surface chatter and goes straight for that low, growly vibration you feel instead of just hear.

Designed by Screaming O, the 4B takes the classic bullet shape and gives it a serious personality upgrade. It’s smaller than a chess piece, fully waterproof, and powered by a super-charged motor with six distinct speeds that lean deep, bassy, and unapologetically intense.

The sensation is noticeably different—less buzzy, more rumble—which makes it ideal for anyone who wants penetration-adjacent depth without needing a larger toy. It’s also travel-friendly, discreet, and compatible with many existing Screaming O products if you’re looking to add a power boost to your current setup.

How To Use It

Use it externally for focused clitoral stimulation, glide it along sensitive areas for a slow build, or press it in place when you want that deep, vibrating hum to do the heavy lifting. Thanks to its compact shape, it’s easy to position during solo play or partnered fun—especially when you want extra sensation without changing the main event.

Add lubricant for smoother movement and stronger sensation. Silicone and water-based formulas are both fair game.

After the Afterglow

The 4B is fully waterproof, so cleanup is refreshingly easy. Warm soapy water or toy cleaner does the trick. Dry it off, tuck it away, and enjoy the satisfaction of owning a tiny object that absolutely overdelivers.
