What are the cutest unique or unconventional ways of expressing love?

Doing a fresh Linux install on your partners laptop

Momma warned me about people like you
Wife: why is my computer not how I remember it being?

Me: it’s my love language!
Nothing says love like surprise LFS.
- Lol.
  
  "But honey, I left you a README file..."

My partner just kinda gnaws on my upper arm. Straight up asked her to stop early days of us dating and she said something along the lines of "but that's how I show I love you" and just kept at it.

10 plus years later it's a wonder my arms haven't callused over. Love that weirdo

Dude, that's not your partner, that's a green anaconda!
- Aw fuck, I've been bamboozled =(
My husband always says, "Stop biting me!" but I think he's faking.
That's my guilty pleasure as well. I enjoy biting.
LOL, yeah I was pretty surprised when I first started dating my wife and she reared her head back like that old cat video and then clamped her teeth down around my forearm. Now I like it.

Pebbling. Giving small gifts or sharing small pieces of content/info that they are interested in

They can even be literal pebbles if they're into that!
- Jesus Christ Marie, they're not rocks. They're minerals
So, uhh... Do you like boulders?
- I take what I can get

Every person and couple has their own so its tough to say. I wake my gf with kisses only which she likes.

I dunno, she seems to like my kisses too.
- What in the 'I'd fuck this guys dead wife too' situation you putting me in 😭

My wife and I tend to pull stupid faces at each other.

you warn them you are aware but aren't complicit to their addictions(hobbies). then you tell them just this time~

you join them anyways.

"I don't condone this but..."

Lights molotov
"Why is there so much yarn everywhere?!"

Two weeks later when the weather cools off - "Can you make a hat for me?"

I once put an entire watermelon under the wipers on my friends car like a parking ticket when I knew they had a rough day at work. They like watermelon.

Washing the dishes, or cleaning up after yourself tells me that you love me and you in a way that words can't express

Gave my brother my mullvad account so he can use a VPN and his PC and taught him how to pirate. Which browser, which sites to trust.. Even walked him through a manjaro install over the phone. I often clean his PC for him when ever I'm over.

Built my ex a cute itx PC in turquoise. Dinky little thing.

Put "never gonna give you up" playing on background every time they leave their PC unlocked

Navigating bureaucracy for someone else

Does infodumping count?

54m here, married for 19 years.

My wife has a very demanding career, so really needs her hobbies to let go of the stress. What I do is listen when she's talking about what has her interests. Then if there is anything I can do to facilitate it, it will suddenly materialize. This is not always something expensive or even something material.

Just before COVID the entire family got into playing D&D. Being an artist my wife went bonkers on painting miniatures. So I made sure she had all the paints and brushes she needed. Plus, the dining room, which is actually our "hobby" room, got a lighting upgrade

How bonkers did she get? This bonkers and there are many many more:

Listen to your SO's friends and [close] family.

Your SO talks to them about what they really want.

Rawr!

(It means I love you in dinosaur)

My wife and I tell each other we love each other an obnoxious amount.

Not so long ago, she developed a throat infection that stopped her from being able to talk for a while. So now we have a new way if saying it, three little squeezes.

I loved it when my ex would act like a child to put something stupid into context.

Killing.
