[Rim] seal fire
The circular flame associated with an ignited loss of containment of highly flammable gas following a spice crazed soirée at the local Indian.
Man, did you see Neville the other night? He had a vindaloo and 8 pints of Cobra. Debbie forced him to shove a cork in it, but the seal failed just as he bent over to tie his laces by the smoking shelter. The source of ignition caught the cloud and flashed back to source. It was a full blown rim seal fire!
