You and Lucas were on top of the roof of some bus thing just talking casually while Steve Harrington was fighting off some Demogorgons or as Dustin calls them "Demo-dogs", Lucas laughed slightly at something you said before he mocked some surfer guy, the stereotypical surfer guy's voice you'd hear in movies.

"Oh, yeah totally Tubular."

He said as he snickered. You laughed along with him despite how serious the situation was, you and Lucas were just goofing around.
