Shortened from the word treacherous, tretch describes something that is dangerous and if desired, cool.

Much like the slang word "sick" it can be used in both positive and negative scenarios.

In the positive sense it can mean fun, daring, chill, etc.
In the negative sense it can mean sketchy, wrong, or terrible
For example:

Positive: "Hey Demarcus, that party was majorly tretch, mann!"

Negative: "Yo man, we have to get out of here. This shit is hella tretch."
