most events in San Francisco are such that the female/male ratio can easily go from relatively high (and therefore favourable) to very low in a relatively short span of time.
The term bronado seems to be a portmanteau of "bro" and "tornado". The term hisicane appears to be a pun on "hurricane". It uses the fact that "hurri" is a homophone of "her" then changes "her" to "his". We could not infer the etymology of bonestorm but we grokked the meaning by the context.
A sausage party: a preponderance of men in a gathering. The term is a vulgar pun implying that men in a group with even a small number of ladies will become sexually aroused (i.e. have boners).
Your interpretation seems natural, but it doesn't fit the context here, where bonestorm and bronado are evidently antonyms. The Urban Dictionary definition, on the other hand, does make sense.
Noah Webster, I might note, is currently spinning in his grave.
It's safe to say that if you need an app to find women, you probably also need one to tell you what to do once they're located. I should start iCyrano.
And I'll create a service for users of Wheretheladies.at that shows them both where the ladies currently are and where CreeperAvoider is sending the ladies so that they can try to stay ahead of the curve and get places right as the ladies are migrating there :)
Now I am getting visions of a bunch of Ladies huddled in a bunker somewhere while hordes of Creeps throw themselves against the doors and windows. Sort of Resident Evil style.
Soon, all the ladies and all the creeps will be sitting at home, afraid to do anything, waiting for the other party to make a move. We've now got Dating Cold War!
The article didn't say exactly how they handle gender-ambiguous names, such as "Kelly." Here's one way:
Using the local census (which knows genders and names), estimate the probability that Kelly is female (in the local area), then weight each "Kelly" check-in by that estimated probability. The final weighted sum for a place is then an estimated expected number of ladies.
From a purely anecdotal point of view, I have lived in 8 different cities in the U.S., including San Francisco, and it by far has the least amount of available straight women (per capita) of those 8 places.
Reminds me of the part in "On The Road" where Sal is at a party with Rawlins and others.. quoting from the book: "Suddenly, there was a great inrush of youngsters from the opera, who just grabbed girls and kissed them without proper come-ons. Teenagers, drunk, disheveled, and excited, they ruined our party."
I hope these guys are smart enough to keep their receipts so they can write off all of the pub crawling they need to do to make sure that it's functioning properly. I might write such an app just to treat it as a 30% off sale on lounge liquor under the heading of "market research".
The knowledge that there are a great group of Ladies in some place can attract a powerful group of men, so we end with a crowded place, the next day everyone is looking for some more relaxed place to contact with someone interesting.
