Hindi/Urdu pejorative slang for the lowest class of male street ruffians. They wear flashy clothes, sport oily hair almost dripping into the atmosphere, annoy your visual senses with their trademark red-toothed smile (acquired through years of betel-nut chewing), smoke heavily and reek of foul body odor thanks to their once-in-a-month showers ritual. Typical hardcore Bollywood wannabes, they never learnt the alphabet but can imitate dialogue-delivery of leading Bollywood actors, especially Sanjay Dutt who portrays these characters in his anti-social movies. They're all rude without exception and think themselves cool but are annoying to say the least. Most of them don't have any real jobs so subsist by occupations which "they" believe are cool and filmi e.g. selling Black tickets outside movie halls, pimping and tour guide for foreign tourists visiting India (they don't know shit about Taj Mahal but can weave stories out of nothing). Complete waste of time for normal people and should be avoided at all costs. They don't belong in residential colonies or any civilized areas because they are real eyesore.
(Mother to Daughter): Beti, don't look sideways. Full of mawalis.
Interviewee: So, is my job guaranteed?
Interviewer: First get rid of this mawali hair-cut and then we can discuss, maybe.
