What does BITS mean in messages?

Back in the saddle

BITS is when a person resumes something they haven't done for a long time. For example, if you return to work after a two-week vacation, you may message your co-workers, "BITS. Thanks for covering my duties these last two weeks!" You will likely see BITS when messaging, whether it be online (e.g., DMs) or via texts (not to be confused with the "bits" word).

Origin of BITS

The "BITS" acronym evolved from the "back in the saddle" saying, which comes from horseriding (dating back to at least the 18th century). In this context, if a rider (e.g., a jockey, cowboy, etc.) fell off their horse or took a break to rest, bathe, relieve themself, etc., they would have to get back in the saddle (the seat attached to the horse) to resume their race, work, trip, etc. As messaging and online activity became prevalent in the late 1990s and early 2000s, netizens shortened the saying to BITS to save time and space when typing.
