Farting

Farting is a used movement of the human bowel that produces a loud sound and a smelly stench. It is also a byproduct of the Slitheen squeezing themselves tightly into fat human skins, known as gas exchange. The slimer newer skin suits have corrected this, although few Slitheen family members are shown using this new tech, as even in the episode The Gift there are Slitheen shown to be squeezed into very fat skins and farting frequently.
