Thanks to social media, secrets have no place to hide.

One unfortunate boyfriend found this out after he made what he thought was an innocuous comment on a Burger King Instagram photo.

He felt the need to share the story of his drive-through experience with his "girl" to the wide world of Instagram. He probably didn't think that anyone he knew would see his comment among the hundreds that pepper Burger King's Instagram.

But lo and behold, someone did see it.

Instagrammer shanlee_rose then proceeded to tag some of her girlfriends in the post, so she could get some backup on the issue.

"F**king knew it," one of her friends commiserated.

"I told you I saw him with a girl," the other agreed. All evidence pointed to the inevitable fact that this guy was about to get roasted alive in Burger King's Instagram comments, of all places.

But the boyfriend wasn't going to go down without defending himself first.

Absolutely savage.

So, with Valentine's Day fast approaching, we'd just like to remind you to not be stupid on social media. Because relationships can be made and broken anywhere.

Even on Burger King's Instagram.
