Riding the merry-go-round 

Riding the merry-go-round* is when a woman seeks to secure a handsome, perhaps wealthy, emotionally unavailable man ("Chad"*) in an attempt to improve social standing (hypergamy), gets dumped, and then she tries again, repeating the cycle. She never learns, all while ignoring guys she has friend-zoned.

After perpetually riding the merry-go-round, the woman eventually finds herself past the flower of her youth, single, and whining on TikTok videos about how "there aren't any good men".

*terms often used by men's advice YouTubers "33 Secrets" and "Entrepreneurs in Cars".

She would do well to stop Riding the Merry-Go-Round and settle down with someone she has friend-zoned.
