 Most of the lyrics in Foo Fighters are nonsensical lines written by Grohl in the 20 minutes before recording began . As the frontman , Grohl explained , " I had seven days to record fifteen songs . I was just concentrating on everything being as together as possible , having everything be tight and in sync . There wasn 't too much time spent sitting in a chair thinking . " Grohl would add that the gibberish was deliberate , given that , " there was too much to say , " following Cobain 's death and , " a lot of emphasis placed on the meaning of the first Foo Fighters album . " Grohl still considered that " the things you write down spur of the moment are most revealing . Now I look at them and some of them seem to actually have meaning " , and revealed that a few songs have lyrics inspired by " personal experiences of the last four or five years " , with the standout being " Big Me " , an " out @-@ and @-@ out love song " to Grohl 's then @-@ wife Jennifer Youngblood that he described as his favorite track on the album . Contrasting with the aggressive and rebellious themes of Nirvana , Grohl had positive and cheery tunes such as " This Is a Call " , defined as " a ' hello ' and a ' thank you ' " to everyone that had played a key role in Grohl 's life ; the playful " For All the Cows " ; and " <unk> " , with a title referencing Mike Watt and lyrics that described Grohl 's " love of hardcore and old school punk rock " .
