A
slang term that combines the concepts of "combustion or burning, in which substances combine chemically with oxygen from the
air and typically give out bright
light, heat, and smoke" and "to unhire an employee" (to dismiss someone from their job). Used to describe both intense criticism and the act of terminating someone's employment.
After that disastrous presentation, the
boss decided to fire him, and the team
spent the rest of the day roasting him in the group
chat.
