The funny thing is that everyone knows what "any" means!
When an American takes about "tail", he does not mean it in the Brazilian sense. It's just standard sex.
Here are two for your American slang vocabulary:
San Quintin quail
Both mean sex with a girl under the legal age for consensual sex. I am not talking about sexual child abuse! In most states, a female has to be at least 16 to engage legally in sex. If she is under that age, the man can be convicted of "statutory rape", a very serious crime. If he is also very young, some times the courts are lenient. Be sure to pronounce "Quintin" as in English, not as in Spanish. KWIN-tin, not Kin-TIN. San Quintín is, of course, a major prison in California.
