This Triceratops has discovered that the consumption of fermenting fruit can had adverse consequences. In other words, it has made him wasted.

I believe this could have actually happened. Flowering plants were well established by the late Cretaceous (having evolved ~80 million years earlier), so they would have produced fruit which presumably would have fermented to produce alcohol. Dinosaurs would have eaten some of these overripe fruit, and you can guess the rest.
