Get a Cornelio mug for your buddy Günter.
An uncool guy that thinks he's hot and cool but he's only a cookie.
"Dude, you're like totally ignoring that little kid that's talkin' to you, dude."
"Who cares, dude. It's only Cornelio"

"Who's that little kid that keeps dancin' like a crab?"
"Dude, it's like cornelio, dude."
