What does G2P mean or stand for ?

Ive heard this more from my female friends for some reason, and never once from my male friends.Not sure why,but when chatting online,users who need to excuse themselves suddenly,brazenly say G2P and leave the chat window open till they come back.Urban slang at its best!
