Murton Poole’s piece, about "ghoulishly cheerful" expectant parents, who would not let casualties stand in the way of their big announcement, was selected from more than 5000 entries world-wide in the Wergle Flomp Humour Poetry Contest, for which she won $US2000 ($NZ3150).
Final judge Jendi Reiter said they appreciated entries made serious points about social change while keeping a "light touch".
"Here, when the cringe-worthy couple’s pink-or-blue explosion goes wrong, they wind up contented with the realisation that children’s identities are not so simple."
Murton Poole, a ski instructor, said she could not believe she had won.
"I’m so grateful to Winning Writers for giving Minnie and Dick, and my sense of humour, a platform.
"I can’t imagine a better place for it than as a Wergle Flomp winner."
Second prize went to Hillary Smith, of Washington State, for Delilah, My Boss, and the third to Alex Barr, of Fishguard, Wales, for Catalog Capers.
