"Belong to"
Definition: A preemptive phrase placed before a location one considers his or her home town.
Example: I belong to Amritsar.
General Commentary: I can't imagine the reaction I'd receive at home if I stated: "I belong to Moline". It places supreme importance and pride on one's family heritage and origin; however, I'm not going to lie, to the American ear it sounds a little goofy.
"Woolens"
Definition: Generic term used to describe winter clothing, typically made of wool (i.e., a thick sweater)
Example: It's supposed to be cold tomorrow, I best not forget my woolens.
General Commentary: This one sounds like it's a leftover from the British and very well may be. Upon checking Wikipedia (yep, now I'm like one of those college students that tries to cite Wikipedia), it's actually a specific type of wool that is "soft, light, stretchy, and full of air", which apparently makes it a good insulator.
"To expire" or "Expired"
Definition: A verb used in place of "to die" or "died"
Example: Anika won't be coming to work today because her father expired over the weekend.
General Commentary: Once you get past the point that a comparison isn't being made to milk gone bad, it's actually a rather peaceful way to refer to the death (or expiration) of a human life.
"Eatables"
Definition: Any item than is fit for human consumption
Example: On some bathroom stalls, I've seen a sign that says, "Don't spit chewing gum or eatables in the urinal or wash basin"
General Commentary: If you're consuming something in the bathroom, all bets are off.
"Cabin"
Definition: Used as a synonym to describe someone's office
Example: "Can we have the meeting in your cabin?"
General Commentary: It took me a while to not think of some cozy little place in the woods with a fireplace. Now, it's just easier to refer to offices as cabins. Having always worked in a cubicle-only environment, I really didn't need to unlearn a behavior to start calling peoples' workspaces cabins.
"This side"
Definition: Used as a greeting following one's name on the phone to announce one's presence, especially on a conference call
Example: "John, this side"
General Commentary: It always makes me smile when I hear this at work; however, I don't think this one has much chance to catch on, if for no other reason than it just doesn't have the same ring to it when used with a western name like "John".
"Double *insert digit*"
Definition/Example: Not so much a word, but when the same number appears back-to-back in a sequence of numbers like a phone number or license plate, it is spoken as "double *insert digit*
General Commentary: Thankfully, my phone number has a "double-two", so if I ever have reason to give an Indian my phone number, I'm always sure to use the "double-two", you know, so they know I've been around a while. It's also a guaranteed and easy laugh when used with another Westerner.
"Prepone"
Definition: The opposite of postpone
Example: "Would request you prepone the meeting by two hours."
General Commentary: Though it's extremely uncommon for a meeting to actually get moved to an earlier starting time in the U.S., I'm all for making this a part of everyday speech. It's almost too easy and for those of us that don't like to speak, it saves words.
"Updation"
Definition: Used as a synonym of the noun "update"
Example: "The updation to the document is complete"
General Commentary: This won't be the last time you see the suffix "-tion" added to a verb to create a noun; these invariably fall squarely in the "work into conversation to make yourself laugh" category.
"Revert"
Definition: To respond, take action, or provide your thoughts
Example: "Would request you revert back to the email"
General Commentary: This one isn't terribly "odd" and is widely used; easily adopted by an expat for professional use.
"Do the needful"
Definition: To follow-up on an outstanding item
Example: "I will do the needful"
General Commentary: I like how this makes each and every task seem important.
"The same"
Definition: Used as a pronoun to refer back to a thing previously mentioned; that is, if pronouns can be used for inanimate objects
Example: "I will revert back and do the needful on the same"
General Commentary: Personally, I like this one. It's simple, it's basic, and I'm not sure there's a real good substitute in American-English.
"Repeat your drink"
Definition: Common method used by a waiter to determine if a customer would like another beverage
Example: "Would you care to repeat your drink?"
General Commentary: This method makes it seem like such a formal affair to have another cocktail and just sounds classier than being asked, "Can I get you another?"
