This meme is likely considered humorous because it plays on the word 'coke,' which can refer to both Coca-Cola and cocaine, a white powder drug. The humor is derived from the juxtaposition of the expected meaning (regarding the drug) with the actual visual, which shows an extremely pale person in a beach setting, implying that 'coke' refers to their skin color rather than the substance. The stark contrast of the person's skin color compared to others on the beach is unexpected, leading to the comedic effect.
