The phrase refers to a particular incident, actual or imagined, involving the previous U.S. President and a model of cooler identified for its sturdiness. The imagery evoked is one among destruction or disregard for a product related to out of doors recreation and conservative consumerism.
The potential significance lies within the symbolism. It may be interpreted as a press release in opposition to perceived elitism related to a selected model, or as a broader commentary on political polarization and cultural divides. Traditionally, the incident, if it occurred, could also be seen as a second highlighting the performative features of latest political discourse.
