Definitions
In US hip-hop slang, 'illy' means cool, fresh, or impressively skilled -- a positive intensifier with roots in 1990s East Coast rap culture. The word played on the negative 'ill' being flipped into a positive (a common semantic reversal in hip-hop). As an adverb it can also mean badly or poorly, but the positive hip-hop sense is the more culturally salient meaning.
That verse was illy -- he went off on the third bar and didn't stop.
Comments
Illy operates in two opposite registers. As a standard adverb, it means badly or poorly — a slightly archaic form of 'ill' used adverbially. But in US hip-hop slang, particularly from the late 1980s and 1990s, 'illy' flipped to mean cool, fresh, or excellent — following the same positive-negative inversion pattern seen in 'bad', 'sick', and 'nasty'. In hip-hop contexts it carries connotations of skill and style, often applied to a rapper's flow or a particularly sharp outfit. Context is everything with this one.
His verse on that track was illy — everyone in the cypher stopped to listen.

Badly; poorly.
"illy" means badly; poorly. It is one of many casual words teens pick up from friends, social media, music or sport, and on its own it carries no particular warning. If you hear your teen use it, it is fair to ask what they mean by it in their friend group, since meanings drift quickly. Asking out of curiosity rather than alarm tends to keep the conversation open and useful.
"illy" is informal English meaning badly; poorly. It is used widely across English varieties. A more formal or neutral equivalent would be something like "badly" expressed in standard vocabulary. A common mistake is to assume "illy" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.
