analphalaxis 

When you eat something so spicy, your bowels cannot breathe and your butthole stays clenched

I had jalapeños on my burger that were so hot it sent me into analphalaxis.

Aww-naphylaxis

1. A severe, potentially life-threatening systemic reaction triggered by a sudden, overwhelming exposure to extreme cuteness, particularly when delivered by a concentrated source such as anime characters.
2. The immunological response is characterized by an immediate release of serotonin and endorphins, leading to symptoms like uncontrollable giggling, teary eyes, a sudden urge to hug or squeeze the source, and in severe cases, fainting or "death" from overwhelming adoration.
3. The condition is believed to be non-fatal, though patients may suffer temporary speech loss (often replaced by high-pitched, unintelligible squealing) and an inability to focus on anything other than the adorable stimulus.

"The convention floor was closed after a fan video of an Eri/Anya crossover caused a mass outbreak of Aww-naphylaxis."
