According to Wikipedia, Spiritual drunkenness
refers to a phenomenon seen in some Christian denominations, particularly those associated with Pentecostalism and the Charismatic Movement, in which individuals who are said to be experiencing intense momentary visitations of—or even possession by—the Holy Spirit exhibit a range of behaviors resembling signs of moderate to severe alcoholic inebriation, including unsteadiness, uncontrollable laughter, silly expressions or gestures, verbal or nonverbal shouting (not typically in the form of glossolalia), sudden intense fatigue, and temporary unconsciousness. The phenomenon typically occurs during Pentecostal and charismatic church services, usually at the prompting of a preacher or pastor, and most often involving multiple members of a congregation at a time, generally after having been "transferred" from one person to another via respiratory blowing or laying on of hands.
You can find several live recordings of this phenomenon on a related question I asked on P&N SE.
