The feeling of male hysteria prior to nutting. Often characterized as histrionic or theatrical behavior such as saying out-of-pocket things to the girl you are hooking up with, getting too into sex, or hooking up with a two-bagger due to excessive horniness.

Often resolved by ejaculation and followed by the feeling of Post-Nut Clarity.
