OK
In the 1840s telegraph communications via Morse code became a reality on th east coast of the United States. Telegraphers strove to use shortcuts in messages which would clarify the messages and complete them more quickly. To this day a letter k _._ or "dah dit dah" in morse code is transmitted at the end of each completed message, which is a question asking "have you got that ok?". The receiver then transmits an r ._. or "dit dah dit" in response which means, message received ok. The telegraphers paraphrased the k and r to "ok" and "roger" which both remain in the common parlance today. Although other more esoteric origins of "ok" exist, they were not in the common parlance at the time that telegraphers, train conductors and engineers popularized their use in the 1840s. The term spread to England and Continental Europe (even non-english speaking countries)as telegraphy spread to them. The principal of establishing a "handshake" in communication in this way (utilizing complimentary status bits regarding segments of messages)is used to this day in advanced digital communication devices.
The Urban Dictionary Mug

Product was as advertised and arrived pretty quickly too! The person loved their gift!
The "Pink Flamingo" colour with white text on a pink background is the best selection for this fine phrase mug. May I suggest you also correct the misspelling of "delightfully" in the default option for a timeless gift.
As always, a great gift.
It looks great. I couldn't have been happier
It’s a mug I would never find in a souvenir shop. I’m a legend in my own home.

This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.

It’s a great way to store my pencils.
I used this instead of condoms It didn’t work and now my nephew is my son
Ordering was very easy and the delivery to a different address then the billing address was done effortlessly with complete correct order. Was delivered before estimated date which was very exciting. Good job well done by all.
Funny stuff! I wish the mugs cost a bit less, I'd buy more. There's an almost unlimited supply of clever slang.
