The sound a cat makes when it meows underwater. First seen in the YouTube video "cat meows underwater".

The action of making the noise a cat makes when it's underwater.
When I put my cat in the bathtub, she stuck her face halfway in the water and meowed, producing a mweb.

After Brooke and I watched "cat meows underwater" we couldn't stop mwebing for hours.
