Yan is not a verb or noun. It is a state of mind. If one is gifted enough to achieve this state of Yan, the carrier of this mind state begins to experience feelings of happiness and confusion. When these two are combined, the results can be marvelous. Be on the lookout for puppies, barneys, and illegal immigrants while in the state of Yan. Be cautious however, as overdosing on Yan is possible. In this situation the Yan becomes increasingly sloppy and is a danger to himself and anyone around him. The Yan is then more prone to getting startled. In his confusion the Yan has been known to pee in public and/or somehow end up at some afterparty with no clothes on. Do not be alarmed however as any amount of Yan will eventually wear off with time.
