Mumbai Sombrero 

Picking up a woman, thinking she is of Mexican descent only to find out after sex that she is from India.

I picked up this chick at closing time and later, while I was asleep, she defragged my PC.
It was a total Mumbai Sombrero.

Moumantai 

無問題 or 无问题

Translates literally as "no problem" but interpreted in English as "relax" or "take it easy" (also written Momentai)

Its a Cantonese phrase made famous by the Bandai show Digimon Tamers, by the Digimon character Terriermon, who it has almost become a trademark phrase.

"Henry, moumantai!" (Literally "Henry relax!")

Moombahcore is basically Moombahton on steriods, mixing Moombahton with the harshness and filth of Dubstep/Brostep. The genre has been mainly underground throughout its existence and has only recently gained mainstream exposure.

Mumbai Madness 

When you eat curry and produce a toilet-filling shit. Usually caused by sloppy, dirties curry which the stomach can't digest.

Nathan: "Boy did I eat a very bad curry last night, very bad indeed."
Jacob: "You might have a case of Mumbai Madness!"
