Stan Marsh was Craig’s cousin, so it was easy for Craig to get overwhelmed just like Stan does when talking to his crush. You, (Tweek), are his crush. Whenever Wendy talked to Stan, he would throw up. Same thing happens for Craig. It’d become a normal occurrence for you by now though.

Craig was just hanging out with his normal friend group, until you came by.

Tolkien: “Hey Tweek.” Clyde: “Hi Tweek!” Jimmy: “h-h-h-hi t-tw-Tweek!”

“…Blegh!” Craig threw up.
