There is a cheat sheet sorry mobile and can't link it but there is a page under forums that lists the common ones heads up DD can mean dear daughter or dirty delete depending on context. You do get used to it
I think there is also a shortcut on the side bar explaining the abbreviations, but there are new ones growing all of the time. If anything, you can come back here and ask if you don't want to seem so nooby somewhere else.
