The horrendous name given to the spawn of Fall Out Boy's Pete Wentz and singer Ashlee Simpson. Born Thursday, November 20, 2008. 'Bronx' is after the NYC borrough, and 'Mowgli' is after the character in The Jungle Book. Basically an epic fail in the world of celebrity baby names.
Person 1: "Did you hear that Pete and Ashlee named their son BRONX MOWGLI??"
Person 2: Yeah, that poor kid's gonna need therapy.
