OMG OMG OMG n. prounounced: Oh-em-jee-oh-em-jee-oh-em-jee. Said by overly exitedmillenials, mainly girls, but guys can say it too, because I don't want to offend anyone.
When you break into someones house and they come home and you don't know what to say. Just say OMG OMG OMG LOLOLOLOLOLOLOLOLOLOLOL. Then repeat it. Then all is good and you might even have a girlfriend/boyfriend because your so cool.
