When waiting in a large crowd to meet someone for a first date, one must not seem too interested. In order to disguise one's anticipation, one fiddles with their cell phone pretending to have recieved either a text message or phone call as the other approaches; thus making the initial hello slightly less awkward and far more nonchalant.
1) While Johnny was approaching, I made a faux call so he wouldn't think I was waiting for him long.
2) "Do I look desperate? I should make a faux call."
