Having a conversation on the phone, where you talk to another human being with your vocal chords.
Tired of chatting with his gf Annie on MSN, Billy decided to be a man and have a phonversation with Annie.
MSN
Annie: Why won't you ever have a phonversation with me?
Billy: Your voice makes me want to throw up. You sound prettier when I can make up a voice in my head for you.
Annie:...we're through.
A conversation pertaining to the senior promenade. Often filled with drama and juicy gossip, promversations are often very interesting to listen to. Topics can include: Dress shopping, how boys asked girls, who will be in which group, and many others. Promversations often take place after spring break and before prom.
I don't know man I wasn't paying attention, too busy listening to everyones promversations.
