A lockscreen couple is what you call two people that share the same lockscreen wallpaper on their smartphone. Usually annoying overly lovey-dovey couples make a picture together and put it as their lockscreen wallpaper to show everyone their love.

Dan: "Omg, we're a lockscreen couple now. That's bare dank."

Stranger 1: "Gasp! We have the same lockscreen wallpaper!"
Stranger 2: "Nooo! That means we're a Lockscreen Couple!"
