McCartney attempted to clear up confusion over the track's name, explaining to GQ
that he didn't want to use the F-word in the title as he's "got eight grandchildren."
He added that the track came about when the songwriting session was coming to a close and he and Tedder were "getting a bit hysterical in the studio" having been confined there for a long time. McCartney suggested light-heartedly that he sings, "I just wanna shag you." They laughed then he added "No, I'll tell you what we can do is, I can make it questionable as to what it is I'm singing."
