scusa

Pronounced "scoo-sa," used to describe the act of hot-boxing yourself using scuba gear, a motorcycle helmet, or any other enclosed apparatus that tightly encapsulates the user's head. The name is derived from an acronym meaning "self-contained underwater smoking apparatus."

Dave: Yo bro, wanna hotbox my ford fiesta?
Bill: Nah, I got this motorcycle helmet right here. Time to scusa this shit up.
Dave: Hell yeah motherfucka'
