An expression used to show excitement or amazement at the magnitude of an event. Generally used as a descriptive, it can also be used in acquiescence, in the sense of showing your friend that you indeed understand how amazing his/her night was. Among friends of a more intellectual bent, the full version--"Too dopamine to copamine"--is primarily used. Can be combined with phrases such as Too legit to quit, too yay to nay, too whoa to no.
