OTP

OTP stands for On-Time Performance, in train lingo. It refers to the number of times that a given train, or railway company, had late trains.
The OTP is usually given in a percentage value, and refers to the percentage of trains that were "on time". Whether a train is on time or not depends on how long the route is. A train from Toronto to New York City has about 10 minutes leeway, but a train from New York to Florida would have to be about an hour and a half late before it was officially considered "late" in the books.

Canadian National had an OTP of 86% last year.

OTP

OTP stands for "Over The Pants." It is often used in the context of distinction for a subset of sexual favors - those that are performed "over the pants."

"Sara is so awesome. She gave me an HJ OTP behind the gym yesterday after class. My underwear was stuck to my leg the whole way home."
"Lisa learned in school that you still need to use a prophylactic when giving a BJ OTP."
