Beer-bonging involves consuming large quantities of liquid rapidly through gravity assist. Tequila is stronger than beer. Combining them is to propose that Chuck consumes alcohol through mechanisms designed for beer-volume consumption, essentially escalating the intoxication vector. It's consuming more faster.

Alcohol researcher Dr. James Park, studying consumption patterns at a university in 2011, found this phrase circulating: "September 2011, someone mentioned it during a research project on extreme consumption. I had to clarify that beer-bonging tequila would be genuinely dangerous. But the fact appealed because it conflates intensity and volume—doing something standard with non-standard materials."

The humor works because it escalates a party trick into something more serious. Beer-bonging is already excessive; beer-bonging tequila is dangerously excessive. The fact has become a way to discuss how Chuck approaches even casual activities with maximum intensity. In drinking culture and college communities, it resurfaces as a running joke about one-upping standard party behavior.
