Common phrasing/construction in MM romance

As somebody who has read a lot of MM romance and a certified word/language nerd, I've noticed a lot of very specific words and phrases that shows up frequently in books across authors and subgenres that I associate very specifically with MM romance.

For example, I cannot count the number of times I've read something like, "What he lacked in experience, he made up for in enthusiasm" in an MM romance, but I've never noticed it in other genres (though I'm sure it's there somewhere!)

This has me curious: Are there words/phrases/sentences that you associate with this genre and generally don't find in other genres?
