[Q]What does BUMPed really mean? topic

The term BUMPed is the only term I am unfamiliar with as I delve deeper into Android modification. I constantly hear the term BUMPed recovery, BUMPed bootloader, This will only work if you're bumped, etc. Everytime I google this question I find people referencing the term bump as a forum post method, nothing to do with android modification.

I appreciate anyone who takes the time to respond and will indeed be sure to give thanks.
