When in a group of people, a silent fart is made by one of the group. Invariably, the smell produces the "Who did that?" quote. When the offending person admits to it, one or more people will let silent but deadlies go, knowing the original offender will be blamed. Thus, the piggy back fart.
One of several potentially awkward sounds created by the body's interaction with air, this one the result of suction from when the lumbar curve of the back is pressed flat against a smooth surface and then lifted, making a loud fart-like sound. Back farts most often occur when having sex on linoleum or when shifting about in a tanning bed.
