All About 

1. A Girl Scout cookie

2. That awkward moment when two horny lesbians are on a first date, and they can't decide whether they should fuck or if it's too soon, so they frantically attempt to set up a pretense of getting to know each other while actually frantically attempting to get laid as soon as possible.

Betty: So how'd your blind date with Rhiannon go?
Penelope: Awful! It was a total All About!
