Just a long, reverberating and multi-faceted fart sound made with my ample arm, sock over the microphone, in a small sound booth. No extra noises. Editted a few together from different tracks to create the 'overlapping' effects of the smaller ones, added a few effects, and was used in a 'toon of mine (kind of 'butthole of the world' volcano going off, suffice to say). Not as wet sounding as i thought it was going to be, though. Can be cropped, etc.
