What does "OT" stand for?

I've been seeing "OT" on this forum for probably longer than I would like to admit and from reading the threads I haven't been able to pick up what it stands for (usually I can figure it out) sooooo someone please enlighten me.

Oh and please be nice

 

It means "Off Topic"

Was that nice enough for ya?......................lol

 

Ha...that was perfectly put...live is good again and I feel much better now...

 

Yes, usually means the topic is not directly applicable to this forum's title, but the poster feels it has enough general merit or interest to the members to bring it to their attention.
