bumburner 

an australian sausage style pepperoni with a lot of little fatty bits and chili. Very spicy and a guaranteed sinus clearer. better than Vick's vaporub. Tastes wonderful in toasted sandwiches. The name 'bumburner' most likely refers to what happens after it goes through the digestive process and burns your butt when defecating.

man 1: g'day, mate. did you 'ave one of those bumburners i gave you?
man 2: sure did, mate. it was hotter than an outback summer
