The act of wrapping yourself around someone, like a koala holding on to a tree, and proceeding to urinate on them while moaning like the marsupial.
Hey, record Joe's reaction when I do the koala on him in the pool later. He will totally freak out when he feels the warmth all around him.

A criminal organization or "gang" mainly based in urban areas of Columbus, OH. The make-up of this clan is mostly Caucasian individuals, and unexpectedly, about 2/3 of the group's population is made up of homosexual men. Their inconspicuous color choice of yellow was made to allow victims feel a sense of comfort with the affiliation. This is quite the misnomer as Yellow Koala activities include crimes such as human trafficking, wellfare fraud, and manslaughter. They are especially notorious for cases of assault towards young children. They refer to this as "friendly" attacks or "Barney" assault.
