The Web site Urban Dictionary quickly moved to define "Obama Baby" after the conclusion of the election as: "A child conceived after (Barack) Obama was proclaimed President by way of celebratory sex," the Chicago Tribune reported Friday.

Beverly Palmer, a California State University psychology professor, said a mini-baby boom stemming from Obama's election is not impossible.

"Being in a thrilling situation, whether it's one of fear or one of joy -- either way -- tends to draw people together," Palmer said. "You sort of reach for each other in those kinds of situations."

The Tribune said it collected anecdotal evidence of election-night sex from a Chicago media research director, a married woman in Georgia and a Milwaukee man who said he and his wife made love on the floor after the returns were announced.

"Yes we can," the Milwaukee man said, echoing Obama's campaign slogan.
