convolution factor 

a scale from one to five (1-5) with five being the most severe, that describes the way someone will adjust their speaking and writing to sound more intelligent or experienced to impress someone they want to date; while intending to sound worldly, people employing a high convolution factor often come across as confusing or just plain idiots
When Linda said she didn't know anything about cars, Brian started speaking at about a convolution factory of 4 to impress her.

havolutionary

(adj.) Describing an entity (especially an AI system) that does not merely undergo evolution as a process, but inherently possesses evolution as a core, self-sustaining property. Beyond "evolutionary" systems that adapt via external inputs or human guidance, a havolutionary system owns its capacity for autonomous, closed-loop self-improvement and meta-level transformation.
Current frontier models are still evolutionary — they improve with more data and fine-tuning. But once an AI starts rewriting its own objectives and architecture without human intervention, it's truly havolutionary — evolution isn't something it does; it's something it has.

In the post-AGI era, we're entering the havolutionary phase: systems that have built-in, intrinsic evolvability, making traditional alignment obsolete.

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.

EBK stands for "Elite Ball Knowledge." 1 In internet slang, "ball knowledge" originally referred to a deep understanding of football/soccer or basketball, but it has evolved into a broader term for having a highly sophisticated, deep, or niche understanding of any specific topic (such as music, movies, or subcultures).
Person A: "That scene was a direct homage to an unreleased 1982 Japanese indie film."
Person B: "Wow, EBK."

Texas is categorized as a swing state in presidential elections, but has voted for Republicans more times than for Democrats in recent history. As such, as demographics change political alignments, some Democrats believe that Texas will vote blue, or Democratic, due to their Hispanic and African American voters, who often align themselves with the Democratic Party's liberal wing.

Blexas has been cited as possible in the upcoming decades, but only if Democrats continue to win the Hispanic vote in bigger margins.
Democrat 1: What is your prediction for the 2024 presidential election?
Democrat 2: Well uh, Blexas!
Democrat 1: You've been saying that since 2008 though.
