Employed often by Sardars or Delhi-ites, especially when irritated or annoyed. Usage varies widely based on the situation, from affectionate to friendly to mildly offensive to I'm-feeling-suicidal-today.
The word has gender specific forms (Male : Khota, Female : Khotee). A gender-neutral version exists too, which works just as well for an entire herd of duffers (Khotey)
Surdie Papa : Khote! That's the brake, oye!!!
