(verb): The act of making an enormous mistake whilst being belligerently inebriated. <Double points if the subject in question's name is actually Jake>
While sitting on the couch with your friend, you vomit on him/her in such a manner that you appear to try to kiss him/her (same gender). Upon getting home, you slip and gash your head open, crawl to the shower, bleed and vomit, and your friends have to take care of you. Thou hast successfully performed the act of "Jake-in' up".
