Biff wasn't feeling so hot after a 2 day bender with his lover, Sally Sue. He started to feel a little like a shell of himself, seeing shadow figures jumping around in the corners of his plane of sight. He figured it might be time to pack it in for a while and recoup. Alas! Lucky for him, he was hanging out with his friend Dick York who is hailed as the King of L&D! Lil Dicki told Biff that "Sleeping is for chumps! You can sleep when you're dead!" So, Biff ripped a few lines, slugged a few shots, and went back for round 3 of the bender and with his dank skank mami, Sally Sue, who was in the bedroom ass up ready to rumble again! Praise Be to the king of L&D!

L.D. Has an amazing personality. He knows how to have a good laugh and have a good time. He's always there to cheer you up when you feel blue. He cusses a bunch and even talks dirty sometimes, but he's super cool. And the one thing he will never do is let down his girl. He always lets her know he loves her and wouldn't do anything to hurt that.
Girl 1: That guy is such a L.D.
Girl 2: I know! I wish he liked me though!

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.
