Thugs when they are trying to pick up your girl: Ah what should I do?
When you realise that they aren't interested in your shrimp of a big tiddy gf: The fuck you mean she isn't the cutest, hotest and sexiest girl in the world?!
The opening through which the urine passes is known as Urethral Orifice or simply, Orifice. Though the term is applicable for both the sexes, the Orifice term is usually used more frequently for the urethral opening of female sex (for male sex it is Urethral Meatus which is.....understandable to say the least ) .
