The guy slapped the girl, and hurt her, so she called the feds, federal workers, which means police, and he did his time in jail, and spent his bread, which came from the word dough, which means money. Bread and dough both mean money. Sorry for accidental double post.

"i slapped my girl, she called the feds" = his irrational decision about being upset about mj, in essence "slapping" taylor swift. "called the feds" is the music industry and media basically prosecuting him for it. "i did that time and spent that bread" = his time away from the us, spending money on his fashion line and music "im heading home, im almost there, hope it will be helpful for you!!
