What does it mean to "drink a lot of haterade"?

A friend recently posted on their Facebook status that she has "apparently been drinking lots of haterade lately"[sic]. Does this mean other people are annoyed with her or she's annoyed with other people? What does this phrase mean?


The term is a take-off on an American beverage called "gatorade," which is what we would now call a "power drink." She is drinking "haterade," appears to not mean that she is not only ingesting "hate," but in a heavy dose, like the beverage.
