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.
