To be pregnant. It comes from the physical appearance of the female's stomach being "pumped up" like a balloon or another round object filled with air.
To be used in the same manner as the word "pregnant":
"She has gone and gotten herself pumped up!"
"Carla is pumped up!"
"When are you going to get pumped up?'
