TK

In online gaming, TK stands for "team kill." A player who purposefully or otherwise kills a member of their own team may be called out for TKing.

TKs occur most often in FPSes like Call of Duty (CoD) and Counter-Strike, when players misfire and accidentally kill members of their own team. If the members of your team grow frustrated with your poor play, bad attitude, or constant noobishness, however, they may TK you on purpose.

In the printing and publishing world, TK stands for "to come." When this acronym appears on a printed page, it means a writer has not yet finished writing a section of a newspaper story, book, or essay, and they plan to return and fill out the section later.

TKs are most often found in first and second drafts, when a writer is still figuring out exactly what they are trying to say and how they want to say it. For example, in the first draft of an essay discussing global population, a writer may leave TK in place of population statistics they plan to look up and insert at a later date.

As social media became more prevalent, those well-versed in publishing began using TK to stand for "to come" on social media platforms and other websites. For example, a writer who is teasing their next book may post an excerpt from the book followed by the phrase "More TK tomorrow."
