Three Toowoomba mates have branded their bottoms while drinking around a bonfire, sparking a major turnout of emergency services.

Luke Moroney, 21, Blaire Cooper, 21, and Joel Austen, 18, decided to call paramedics after waking up at lunchtime yesterday with hangovers and severe burns to their bum cheeks.

The trio had to peel the underwear off their blistered backsides and wait for help but a miscommunication caused multiple paramedics, fire crews and police to respond to an "explosion-type incident with multiple casualties''.

Mr Moroney did not know why the group had decided to brand themselves with the red-hot fire poker at a party in the early hours of November 6.

"I remember putting it [the poker] on my bum cheek then running straight to the dog water dish [to cool off]. Now I have to go to the doctor tomorrow because it is infected," he said. Paramedics left the sore trio with some antiseptic cream and dressings.
