ONPS (Old Nut Puppy Syndrome) is a disease caused by not allowing a male dog to ejaculate for multiple years before allowing to breed. The resultant puppies are frequently born with physical or mental deformities, often resulting in still births. ONPS is easily avoidable by allowing the stud to ejaculate with owner assistance before copulation with fertile bitch.
Man 1: Dude my puppies were all born inside-out. There's just organs all over my floor. What the fuck happened?

Man 2: Sounds like ONPS. I told you, you should jerked off your dog before you let him mount her.

ONPS, or Old Nut Puppy Syndrome, is a disease in which puppies are born with severe physical deformities (often fatal) as a result of using old sperm during insemination. Allowing your stud to ejaculate through assisted methods prior to copulation is the only proven preventative technique. The chances of ONPS are increased exponentially as the time (in months) between last known ejaculation and copulation are increased. Veterinarians recommend massaging the penis or felatio of breeding studs every three months to ensure healthy litters.
Man 1: Dude my puppies were born inside out. What the fuck?

Man 2: I told you, you should've gave Fido a handy before you bred him. This is classic ONPS.

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.
