When a group of musician get together, smoke an incredible amount of hash, and spontaneously play music without having any idea what direction anyone is going in musically. The end result is usually a song or noise. This is a method used by all the classic rockers of the last generation. It can be easily repeated without the bong, which i prefer.
"Hey I just started a band and we're going to do a shitload of covers until we are at Bong jamming Level."

Making love to someone from behind in a car standing in the back seat while they are kneeling on the center console. The ‘giver’ makes noises like a car engine.

A variation of the Blow Job, where one partner lies on their back on a bed (or massage table or baby grand piano) with their head hanging off the edge, mouth agape. The second partner stands bedside and proceeds to penetrate the lying partner’s hanging mouth with their penis and performs a vigorous humping motion, preferably to ejaculation.
Etymology - the standing partner JAMs their penis and balls into the lying partner’s face (i.e. their MUG)
