The Davis Trinity is a ritual most often performed by UCD undergrads. It entails the consumption of three of the (arguably) strongest drinks in Davis in one night:

Ideally, this feat is accomplished in one night and as quickly as possible. It is generally advised to prepare ahead of time (eat, drink a lot of water) and to not drink any other alcoholic beverages before embarking on the task. A determined group of adventurers can be expected to complete the Trinity within 90 minutes, even if they are drinking at a leisurely pace.
