The insult 'mubarak idris' is the english pronunciation of the arabic < مثلي الجنس هو الذي تمتص القضيب > which means 'the gay one who sucks penis'. It basically means, a dumb homosexual guy who puts people's fauzan's in his mouth.

Aabis: hey, guess what Raamy did to thumi yesterday
Darrel: what?
Aabis: he sucked thumi's dick!
Darrel: ha, such a mubarak idris! Y'know Raamy actually sucked mine too, i forced him – he's so gay.
That was when Aabis started to doubt Darrel's heterosexuality
