To make a 'booty call' to that girl you had a one night stand with that time, (whose name you couldn't remember) so you just pressed the letter 'a' a few times when it came to putting her in your phonebook - meaning she will be first alphabetically (as would anyone called 'Aaron Aaronson).
Paul: Man, I'm in need of some female company, I might give Aaron Aaronson a call. I couldn't remember her name, so in the morning when we swapped numbers I just pressed 'A' a few times on my phone, so in my phonebook she'll be first in the list.
