Please sir, what is a Bump as being used in this Forum?
Maybe after your answer, I can decipher when a bump is said to be old.
Incase I may not, you can assist me also by saying when a bump is old.
Bump is a "Post" done by the original poster of the thread to Rank up the thread at the thread to the 1st page of the Board if it's on 2,3,4, etc Pages of the Board.
For this very reason, most people look at the active threads that are on the 1st page and maybe 2nd or 3rd but not dead topics that are present on other pages of the board.
Look at this thread for example - The moment before i made this post quoting yours the thread was on the 2nd line of the page (Excluding pinned posts) "

And after I made this post - The thread came to 1st line on the board (Excluding pinned posts)
"screenshot link will be here"
