Religious practice among Pentecostalists and charismatics involving speaking in what sound like other languages or "spiritual language"
I arrived in church late, and the whole congregation was speaking in tongues. I couldn't understand a damned thing, but it was impressive

typing (or texting) gibberish. Comes from typing in frustration, hitting the keyboard, or accidentally leaning on it. A posting or sent mail or text shows up indecipherable.
Looks like Megan is speaking in tongues again. I checked her last facebook post. 3am, nothing but garbage. Must have fallen asleep on the keyboard. Drunk. Again.

Speaking in an unknown language. That is to say it is unkown to the speaker but is not unknown to God. Speaking in tongues began on the day of Pentacost by Jesus' disciples. The purpose of speaking in tongues (in my view) is to issue prayer that encompasses issues of life unknown, but needing to be dealt with. Speaking in tongues may seem foolish to the average person (even the average Christian), but if you desire wisdom, it is the thing to do.
