1) a baby delivered during a prom dance and tossed in the trash.

2) a baby that results from post-prom activities.
1997: Melissa Drexler, who slipped into the bathroom at her senior prom, delivered a 6-lb. 6-oz. baby boy and tossed him in the trash basket with the soiled paper towels in time to get back to the party. She asked the disk jockey to play her favorite Metallica song and danced with her boyfriend. A student told a reporter later, "She seemed to be enjoying herself for just delivering a prom baby."

Family Guy musical number based on the true life story of a New Jersey teen-ager who gave birth in a bathroom stall at her senior prom, delivered a healthy boy, cut the umbilical cord, choked him and put him in a plastic bag that she knotted and threw away.

In the midst of it, a girlfriend who had heard sounds from the bathroom stall asked Miss Drexler if she felt ill. The Prosecutor said she replied: ''I'll be done pretty soon. Go tell the boys we'll be right out.''

A few minutes later, leaving blood on the floor of the bathroom stall, Miss Drexler went to the dance floor with her boyfriend and prom date, John Lewis, ate a salad and danced one dance.
