Early Dick

Having sex before going out on the town.

Leaving work early to go get some.
Kind of like a noon'er.

BP: What time are we going out?
HB: I need to finish up and get some early dick.
BP: So five minutes after you get home.
HB: Going for the extra 30, 7 minutes.
BP: Ok, get the early dick but don't forget to double up that shit tonight!
