Well,there is a secret messege,i can't really explain it very well,but i will try.
the "if" in the begining is supposed to sound like the letter f.
then,"you" in the song,af…ter if,is supposed to be the letter u.
next,see in "seek" is supposed to be like the letter c.
lastly,the k in "seek" mixed with the a in "amy" make the letter k sound..
and then,add me,as the end of "amy".
so basicly,she was trying to spell out f*ck,then me,so its f*ck me xD.
and the song goes 'All of the boys and all of the girls are begging to "if you seek Amy"'.
hope you get it now :p ( Full Answer )
