It went well and one of the dancers was beaming as she strolled off the field, but then out of nowhere she vomited everywhere.
And just in case the fans watching at home missed it, the Riverdogs uploaded the gross-out footage to social media.
What made her ill remains unclear, but viewers have noted that the team runs a “Thirsty Thursdays” promotion.
Others have suggested that it was simply ball-park food combined with the sudden physicality of dancing.
Regardless, her unfortunate outburst is being used as a Twitter meme to express sudden disgust.
Some fans took issue with the minor-league team for sharing the video on social media.
However the fan herself, named Bonnie, joked on Twitter that she gave “all she’s got” for her team.
