When you take the new famous drug 'meow meow' and get a little angry instead of growling like a dog you.. it's called meowling like a destressed tabby.
Fully you were definitly meowling last night dude! you sounded as tho you were being shagged by tabby cat bro!!
A Meowling is somebody who followers the Meowism religion, is a believer of Meowbahh, AND uses catgender pronouns. A MeowIST would be somebody who does NOT use Catgender pronouns, but is however a believer of Meowism and Meowbahh.
