chat activity involving three people. no more. no less. 3 women. 3 men. 2 women 1 man. 2 men 1 woman. whatever the grouping - all must engage in chat activity with one another for the activity to be a 'menage a chat'.
This can be done via SMS, instant messenging clients, facebook, or other social media platform.
Lisa said it was fun having a 'menage a chat' with Rich and Trisha when planning Lovely Lorraine Lush's Birthday Party. Similar to Menage a Tweet but not specifically tied to twitter.
