The chance that a lesbian, especially a lesbian couple, will come through and show up for a social gathering. Everyone knows that lesbians are intelligent and reliable on the job and for sporting events, but when it comes to meeting for happy hour, going out, or going on a quick trip, the % chance that they will show up isn't consistent, it's circumstantial. Thus, every event that a lesbian has agreed to come to has a % chance of lesbiatation for arriving on time or at all.
Well, there's a 90% chance of lesbiatation, I think they'll come.
