Introphobia
Introphobia ɪntrəʊfəʊbiə is the irrational fear of leaving a message on an answering machine due to the possibility of ending up on the intro of a (most commonly Rap or Hip-Hop) album.
THOT called me last night but I couldn't answer so it went to voicemail. I'd tell her to leave a message but she has introphobia.
