The Cupcake Lady is a minor character on True Capitalist Radio. She was first mentioned in April 2017, when Ghost stated that the woman who lives across the street from him gave him cupcakes out of the blue, a gesture which Ghost appreciated, eating the cupcakes on the air and stating "they were like crack".
On May 3rd, 2017, Ghost would state that the Cupcake lady is trying to ruin his marriage on ghost.report, confirming the trolls suspicions. He stated that the reason he had to abruptly cancel the show scheduled for that day was due to the fact that the cupcake lady had brought him Cinco De Mayo-themed cupcakes, presumably in an attempt to receive piece of the the Mr. Ghost Special, and Mrs. Ghost had seen it happen, causing her to act jealous. Ghost kept the cupcakes and ate them on the air on May 4th.
On a more positive note (at least from his perspective), Ghost has used this female attention as evidence that he knows what he's talking about when he gives romantic advice to today's fruitbowl, cartoon fetishist men on the show.
Ghost's first mention of The Cupcake Lady on April 2017 quickly led to many trolls accusing Ghost of cheating on his wife, making him quite furious. Things only got worse since Ghost kept the Cinco De Mayo cupcakes from the incident that caused an argument with his wife and ate them on the air on May 4th, once again loving them, and making The Cupcake Lady the most popular target of splices and Twitter names for a short time.
The Cupcake Lady can be considered a real-life troll due to the strife she has caused in Ghost's marriage.
