Best definition
Nickname for catnip. Specifically, the fresh, little-green-buds kind that drive most cats utterly insane. The dried-powder junk from

the grocery store need not apply.

“Dude, your cat is totally zoned out on the wibbleweed, isn’t he? He’s staring at me with big moon-eyes.”

“Yeah, it’s the good stuff. Keep your hands clear if you value your skin.”
