I decided to turn a few puns from above, into one big one. So, here it is.
Your girl wants to meet up at the P.A.R.T.Y house. She never emails or calls about accepting the invites.
One of the guests argues about her doing that, showing up without a R.S.V.P.
Not wanting to start a war with her, you both look at her with annoyance. Then you throw your hands up and say to the group, "F.U.C.K. and I.T, just letter go."
