Klingons.
Singular : Klingon.
Undiligent wiping of the anus post defecation causes excrement to remain on the anal
follicles. Eventually the excrement will dry and form tiny spheres that attach themselves to your anal follicles.
In extreme cases the "
klingons" can encompass many follicles which can make them painful to remove.
Worf: A very large "klingon".
