A term to describe a male being (of sorts) that is continuously 'creeping, lurking or lingering' in your personal space, especially after politely asking them to 'go away'.

Has a complete disregard towards self-hygiene and cleanliness.

Is a being/creature that will stalk you not only via cyber networking but physically. Once the 'Illes' targets his pray, he will drop neverending euphemisms, sexual 'pesting', harassment towards the guy - irrelevant of their sexual orientation.

Will download your (the victims) personal online photos, e.g. Instagram/Facebook and edit them to his liking without any permission whatsoever, moreover, he will then 'resend' the edited photos back to the victim in the hope that the victim is psychologically twisted and finds it endearing.

Other Forms of Illes include:
Verb:Illesed
Adverb: Illesing
Synonyms: Piece of shit, Dirty Queer, Fat dirty slob, Le Bas/ Breno hunter

Did you see Liam 'Illes' ? He was lurking again.

That Illes put ruffe in my drink last night, called the police but they couldn't do anything. They also fell victim to 'the creature'.
