Got To Go Take A Big Poo. This is a way to give a reason as to why you are leaving the computer and not returning. Not to be mistaken for "brbigtp", which means you will be taking a much smaller poo and that you will be returning to the computer once you have finished. Gtgtabp implies that the poo is bigger and that you will not be making your way back to the computer after the poo has been taken.
