A no-disqualification, no-countout match where anything goes. Falls count anywhere — in the ring, in the crowd, in the parking lot, in catering if you feel like it. Wrestlers usually come out in street clothes instead of gear to sell the 'this is personal, not a wrestling match' vibe. The street fight is the catch-all stipulation for feuds that have gotten too heated for a normal match. It's also an excuse to use every weapon under the ring.
"They're brawling through the crowd, up the stairs, into the concourse. Someone just got thrown into a merchandise table. This is a street fight."
