A fat girl who thinks shes hot because she has big breasts, but really no one cares that she has big breasts cuz they rest on top of her big fat belly like two sacks of sand. Normally has secret low self esteem which leads to excess eating and acting like a dirty sket
Can also be used to describe a male who never washes and is generally a bit of a crackhead
and probably homeless.
Look how tight that girls clothes are, shes got to weigh at least 15 stone! What a skanky ilona!
I used to hang out with James before he started hitting the pipe and turned into a total ilona.
