Weird but cute things couples do

I just saw this video and it shows some weird but cute things some couples do so I just started thinking what are some weird things you and your SO do that's strange or weird but it's cute or funny to both of you? Ours is I always fart on his leg. He hates it but I find it funny then he tries to start a war with me by farting on my leg. It's a never ending thing but we always laugh😅😂
