My best Friend and her boyfriend are ALWAYS lovey dovey around our group of friends and ALL of us are annoyed?

I HATE that too! I'm only 15, but my bff is the SAME way. And they're too young to be draped all over each other like that, I say. Ya wanna know what I did? I invited her to a girls night at my house with just the two of us. Then about an hour later, I invited my boyfriend over and while we were watching a movie, I sat on his lap and we made out like the entire movie. She gave us the dirtiest looks. Haha. Then later we went to the park at like, midnight, and me and boyfriend held hands and kissed the entire time and she got so pissed at me. I told him to, like, steal me away from her all that night (he was in on it) and we climbed a tree together and she was alone on the swings. She, actually, learned a lesson and stopped being all lovey dovey. So there's an idea(:
