There's an element of flesh to it. It can lead to disorder and rampant emotionalism. People want to do it, and so they do. It's supposed to be a gift from God and not something that you can obtain through works (Assuming that Pentecostal/Charismatic interpretations of the Bible are least to close to right). Repenting a lot is not necessarily a way to obtain that gift. So when the churches like Oneness Pentecostals try to get everyone to do it, you get imitators.
I know many Pentecostals. I've heard stories of prayer teams telling others to 'fake it'. It's a bit of a problem in the churches. The pastors who are worth their salt want the experience to be as legitimate as the phenomenon can be. Despite the efforts of doctrinaire Pentecostals to reign them in, this 'fake it' attitude seems to be super common in their church.
I've been to their churches. One of my neighbors does this 'lalalalalalala' thing. It's clearly her trying to do what the 'real' tongue talkers are doing. Her husband can really do it, and I she's trying to live up to the example he set.
Even so, I wouldn't necessarily discount the validity of it. Imitation is different than the genuine experience (see >>563595 ) which spawns all of the imitation. It's like astral projection or something. You could explain it in purely natural terms, but why? Because no fun allowed?
