(sylissa, pronunciation; sill-iss-uh)

1. A colloquial term for someone who is a slippery bugger—generally of the female persuasion—who uses any means to get her ends. A Sylissa is usually highly attractive and not above exploiting the power she has over other people because of this—be they male or female. She is highly intelligent and doesn't always bother to hide her sociopathy, believing people to be too foolish and unobservant to realise that they are being manipulated. In most cases this is a true belief, due to the fact that she is a true Master at what she does. She is very creative and not scared to play the long game. Sylissa's tend to have a darkness inside that scares even themselves upon occasion.

2. A woman hated by those around her for no apparent reason. A cursed being.

3. A colloquial middle-class (brit.) term for a serpent—or indeed a person with serpent like qualities.

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.

Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
