So, pet peeve #1 is
the stupendous cliché of describing sex like it's a dance.Pet peeve #2 is something somewhat less serious (occasionally I'll be able to forge ahead with reading a fic even if it comes up) - it is any variant of the phrase "chocolate brown orbs" in reference to eyeballs.
This is a cliché with several layers that need to be peeled apart like a frog on the dissection tray:
1. Orbs. This might be a result of that idiotic "wolf" thing that was big in fandom a few years ago (is it still around?) where simple words for body parts get replaced with more flowery, poetical words that achieve the result of being unnecessary, inaccurate, and annoying - or it's just a result of not wishing to overuse the word "eyes" and unfortunately picking a word that's still unnecessary, inaccurate, and annoying.
"Orb" refers to a three-dimensional sphere. See, that's not what we're looking at when we look someone in the eyes. Orbs, or eyeballs, are weird, squishy things. When you look someone in the eyes you don't want to be picturing looking deeply into something that looks like
this. (It's a guy with a cow eyeball in his mouth, not that gross, but probably NSFW.) That's why we have eyelids and eyebrows and things: so what we really wind up seeing is the gorgeously colored iris and mysterious pupil, set off by the various subtle configurations of eyelid and eyebrow that are what really telegraph the soulful emotions that fanfic writers are big on writing about.
I get that sometimes you've written "eyes" way too many times in the preceding paragraphs, you need another word, fine. Just don't use "orb," unless you want to conjure up images in your readers' minds of round squishy things set in the hollows of a naked skull. Or
buttocks. (Scroll to the bottom of the page.)
2. Chocolate brown.
Gah.
I just.
GAH.
I can't find it anymore, but I read a badfic years ago, I believe Hermione/Viktor, which featured chocolate eyes (hers) and caramel eyes (his) that met and swirled together into a veritable sundae of passionate flavors. The worst part is they actually wrote the 'sundae' line - in complete seriousness.
So, I think this is enough to sum up why describing eyes in terms of ice cream flavors is a bad idea. Anyway, chocolate comes in tons of shades, so in the end the epithet is ultimately meaningless, and just exposes lazy writing.
You'd be better off writing "looked into his angry eyes" or "looked into his eyes and flinched at the anger in them." Most of the time the focus is going to be on the emotions anyway - what does color have to do with it? Unless it has actually consciously registered with the POV character that s/he is looking at brown eyes - s/he's studying their color or the eyes are some stupendously stunning shade that's obvious the way wearing a garish striped suit would be obvious - there is very little purpose in pointing out eyeball color every damn time you write about said orbs.
