look up anything, like your first name:
1. 14 and a half
A phrase used to interrupt your friends without making them stop what they're saying. A code word for reminder is necessary.
Sara: <telling a long story about whatever>
Ashley: 14 and a half lawn gnome!
Sara: <continues to tell story>

.... a while later

(Either Sara or Ashley): So... 14 and a half lawn gnome.
<then Ashley gets to tell her story.>
