Candlejack
Candlejack is a text-based joke format built around a villain from the 1995 animated series Freakazoid, whose lore says he kidnaps anyone who says his name. Posters type his name and then cut the sentence off mid-word to fake being snatched mid-post, a bit that took hold on 4chan and other forums in the mid-2000s.
Overview
Candlejack, sometimes styled Candle Jack, is a hooded villain from the Warner Bros. animated series Freakazoid whose gimmick is snatching anyone who says his name out loud1. Online, that in-story rule turned into a writing bit: a poster types "Candlejack" and then chops the sentence off mid-word, as if a rope had just yanked them away from the keyboa--3.
The joke works best in plain text, which is why it took hold on imageboards and forums rather than in image macros3. Its recognizability comes from the abrupt cutoff itself, so replies often mirror the format back, stacking interrupted sentences into a running thread gag4.

How to Use This Meme
Typical use is short: write a normal sentence, drop "Candlejack" into it, then cut the next word off after a letter or two to fake being grabbed. Common conventions include ending on "OH FU", "kind--", or a single dangling letter, and follow-up posters often reply with their own interrupted sentence to keep the bit going23.
