Ivern refers to weed.
Also, when you've smoked weed, you become Ivern.

Ivern is a character from League of Legends, the saying is inspired from his character, our long legged happy tree friend with his soothing voice.
"Hey, wanna go smoke some Ivern?"
"Sure, let's get faded af bro"
Some later..
"I'm Ivern af.."
"..."
"Can you make me some pasta?"
