This is Summer Fling 101 stuff. Until you have that conversation about not boinking other people, refrain from tagging your fling in a picture of a heart you carved in the sand. You don't know what they have cooking, and things could get ugly for you if she's "on a break" from a backup linebacker at Vanderbilt. When she goes back to school, he's going to have questions about that heart in the sand, and you'll end up hanging by your ankles from a bridge. On the plus side, that POV shot of a football player dangling you over the Cumberland River is going to be an absolute banger on Instagram.
