1) The male equivalent of a daddy's girl; Any male (kid, teen or, adult) who's very close to his father. He is, however, typically spoiled and bratty, thus creating the difference between a male closed to their father, yet not a "daddy's boy." Often times the male who relies solely on daddy to pay for anything or get anything from the father. (This includes rent, bills, ect.) (Reference Ted Gunderson (Fallout: New Vegas.)
2) A male (kid, teen or, adult) who is excessively influenced by or excessively attached to his father. Similar to a mama's boy.
