It's just to get it back to the top if the forum
O. I didn't know either. Thought it meant like, "hell no!" Lol or whatever
It stands for "Bring Up My Post" the more comments a question has the closer to the top it goes.
Cute! Lol I'll have to use that one day to keep my post active.
I do it a lot bc no one ever response to my posts. Honestly don't even know why I'm on here!
