mom prom 

A “mom prom” is when a mother chapperones her child’s prom and it’s more about the mom and her hideous dress. The mom was never invited to prom and she’s making up for not getting invited. The daughter or son is mortified by their mother, how she looks and acts at the prom.

The dress she was wearing made her look like she was a contestant from Toddlers and Tiaras. The dress had giant poofy sleeves, way too many sparkles and a ribbon tied in back. The dress made her look like she was going to a “mom prom”.

Mom in the Prom 

When you get dropped off at prom but then, your mom's favorite song comes on, she gets all the attention, and then the next day everyone talks about how cool you're mom is.

Me: "There goes my mom dancing again."
Friend: "What? She's so cool!"
Me: "Yeah, cool for a Mom in the Prom."
