Munstered

One of the insults directed at Becky in "The Little Giants" is, "She's hot to trot, but she's still gotta squat."

The episode of Happy Days where Richie falls for a divorcée taught me that "hot to trot" means "DTF." I never understood the nature of the insult. Was he calling her a slut? Is she a slave to her biological urges because she's a woman? Did he not know the meaning and think "hot to trot" just means "wants to run [with the boys]?"

I know I'm over-thinking it, but this particular insult has been an earworm my entire life.

Dear Tommy,

What does "hot to trot" have to do with sitting down to pee?

Sincerely, My Childhood
