When you get past fourth base on a chick, (or on a guy if your queer). This is when you place your meat in her ass. Commonley refered to as Puerto Rican style.
Hey TJ, I fith based this chick on saturday night, Puerto Rican style. I pulled out and there was a peice of corn on my helmut.

The act of propping open a woman's anus with a metal ring and placing one's testicles in her. Remove the ring and the testicles will be trapped inside her until the women releases her sphincter and passes stool. The act of the woman shitting one's testicles out is called "fifth base".
My girlfriend wanted a little more than anal sex last night so i decided to take her to fifth base. The ring hurt her but not as much as her ass hurt me!

The absolute ultimate feminine honor --- a sign of trust and permissiveness that's actually even greater than her allowing you access "down there" --- namely, a chick's giving you a copy of the key to her house or apartment, so that you can just gleefully waltz right on in and "get it on hot 'n' heavy" with her anytime you desire.
Fifth base is actually kind of a "mixed blessings" spot to reach on da ol' playin'-field... yes, it is indeed a wonderful thing if a nice lady entrusts you with the "magical strip of brass", but like all situations like this, "with great power comes great responsibility"... you'll want to "guard that key with your life" --- securely tether it to a sturdy key-ring and/or chain, keep it hidden or locked up when you're at home, and never let it out of your sight when you're traveling... there are far too many less-than-honorable individuals out there who might wanna access said key for equally-less-than-honorable purposes!
