Tiny balls of pooey toilet paper which attach themselves to the hair's in a man's/woman's ass crack. Otherwise known as "cling-ons" or "poo balls".
Man: I want you to rim my ass baby.
Woman: Ok, bend over baby
Woman: Awww man, you could've at least wiped your ass properly - I can see winnits in your crack!!
Man: So I guess that means no rimming for me!?

Winnit
A tiny particle of faeces that sticks to the hairs on your anus, causing a small amount of pain when removed.
Usually occurs when the anus is not cleaned correctly after excretion.
Oh my God, look at the size of that winnit. IT's HUGE!
