Excessive PDA.
So there's cute, then there's gross. And much like all good things, you don't want to overdo it.
We get it, you've got a new boyfriend and you think he's the bees knees. So do we! But don't overdo the posts about him, and please, please don't post pictures of you sucking face.
A little PDA is totally fine. But don't blow up our feeds with it. And this applies to other social media too, like Instagram and Snapchat.
Some things are best kept in the bedroom. Don't blast it out on Facebook. Don't give your grandma a heart attack.
Bonus:
Please stop posting the first-person view pictures of you holding your lover's hand while you're walking on the beach.
Please stop.
